feat: Expand schematic component support from 3 to 13 types + plan dynamic loading

Issue #26 Follow-up: The original fix only supported 3 component types (R, C, LED).
This expands the template-based approach to 13 types while planning for unlimited access.

**Expanded Template (Option 1 - Immediate Solution):**
- Added 10 new component types to template
- Passives: R, C, L, Crystal (4 types)
- Semiconductors: D, LED, Q_NPN, Q_NMOS (4 types)
- ICs: OpAmp, Voltage Regulator (2 types)
- Connectors: Conn_2pin, Conn_4pin (2 types)
- Misc: Switch/Button (1 type)

**Components Now Supported:**
1. Resistor (R)
2. Capacitor (C)
3. Inductor (L)
4. Crystal (Y)
5. Diode (D)
6. LED
7. NPN Transistor (Q_NPN)
8. N-Channel MOSFET (Q_NMOS)
9. Op-Amp (U)
10. Voltage Regulator (U_REG)
11. 2-pin Connector (J2)
12. 4-pin Connector (J4)
13. Push Button/Switch (SW)

**Implementation:**
- Created template_with_symbols_expanded.kicad_sch with all 13 types
- Updated TEMPLATE_MAP with comprehensive type mappings
- Updated project.py to use expanded template by default
- All tests passing (13/13 components added successfully)

**Future Plan (Option 2 - Dynamic Library Loading):**
- Documented comprehensive plan for accessing ALL KiCad symbols (~10,000+)
- Dynamic loading from .kicad_sym library files
- S-expression injection approach
- 6-8 week implementation timeline
- Maintains template fallback for compatibility

**Files Added:**
- python/templates/template_with_symbols_expanded.kicad_sch
- docs/DYNAMIC_LIBRARY_LOADING_PLAN.md

**Files Modified:**
- python/commands/component_schematic.py (expanded TEMPLATE_MAP)
- python/commands/project.py (use expanded template)

This provides immediate value (13 types vs 3) while we plan the long-term
solution of unlimited symbol access through dynamic library loading.

+# Option 2: Dynamic Library Loading Plan
+
+## Executive Summary
+
+Replace the template-based schematic workflow with dynamic symbol loading from KiCad's installed symbol libraries. This would eliminate the 13-component limitation and provide access to ALL KiCad symbols (~10,000+ symbols from standard libraries).
+
+**Current Status (Option 1):**
+- ✅ Template-based approach working
+- ✅ 13 component types supported
+- ❌ Limited symbol variety
+- ❌ Requires manual template updates for new types
+
+**Proposed (Option 2):**
+- 🎯 Dynamic loading from `.kicad_sym` library files
+- 🎯 Access to ~10,000+ KiCad symbols
+- 🎯 No template maintenance required
+- 🎯 User can specify any library/symbol combination
+
+---
+
+## Problem Analysis
+
+### kicad-skip Library Limitation
+
+**Core Issue:** kicad-skip **cannot create symbols from scratch**. It can only:
+1. Clone existing symbols from a loaded schematic
+2. Modify properties of cloned symbols
+
+**Current Workaround:** Pre-load template symbols in schematic file
+
+**Proposed Solution:** Load symbols from KiCad's `.kicad_sym` library files, inject them into the schematic's `lib_symbols` section, then clone from there.
+
+---
+
+## KiCad Symbol Library Architecture
+
+### Symbol Library File Format (`.kicad_sym`)
+
+KiCad symbol libraries are S-expression files containing symbol definitions:
+
+```lisp
+(kicad_symbol_lib (version 20211014) (generator kicad_symbol_editor)
+  (symbol "Device:R"
+    (pin_numbers hide)
+    (pin_names (offset 0))
+    (in_bom yes)
+    (on_board yes)
+    (property "Reference" "R" ...)
+    (property "Value" "R" ...)
+    ;; Graphics definitions
+    (symbol "R_0_1" ...)
+    (symbol "R_1_1"
+      (pin passive line ...)
+    )
+  )
+  (symbol "Device:C" ...)
+  (symbol "Device:L" ...)
+  ;; ... thousands more
+)
+```
+
+### Standard KiCad Library Locations
+
+**Linux:**
+- System libraries: `/usr/share/kicad/symbols/`
+- User libraries: `~/.local/share/kicad/8.0/symbols/` or `~/.config/kicad/8.0/symbols/`
+
+**Windows:**
+- System libraries: `C:\Program Files\KiCad\9.0\share\kicad\symbols\`
+- User libraries: `%APPDATA%\kicad\8.0\symbols\`
+
+**macOS:**
+- System libraries: `/Applications/KiCad/KiCad.app/Contents/SharedSupport/symbols/`
+- User libraries: `~/Library/Preferences/kicad/8.0/symbols/`
+
+### Standard Library Files
+
+Common libraries (each containing 50-500 symbols):
+- `Device.kicad_sym` - Passives (R, C, L, D, LED, Crystal, etc.)
+- `Connector.kicad_sym` - Connectors (headers, USB, etc.)
+- `Connector_Generic.kicad_sym` - Generic connectors
+- `Transistor_BJT.kicad_sym` - Bipolar transistors
+- `Transistor_FET.kicad_sym` - MOSFETs
+- `Amplifier_Operational.kicad_sym` - Op-amps
+- `Regulator_Linear.kicad_sym` - Voltage regulators
+- `MCU_*.kicad_sym` - Microcontrollers
+- `Interface_*.kicad_sym` - Interface ICs
+- ... 100+ more libraries
+

+
+## Implementation Strategy
+
+### Phase 1: Library Discovery & Indexing
+
+**Goal:** Build an index of all available symbols and their locations
+
+**Implementation:**
+```python
+class SymbolLibraryManager:
+    def __init__(self):
+        self.library_paths = []
+        self.symbol_index = {}  # {"Device:R": "/path/to/Device.kicad_sym", ...}
+
+    def discover_libraries(self):
+        """Find all KiCad symbol libraries on the system"""
+        search_paths = [
+            "/usr/share/kicad/symbols/",
+            os.path.expanduser("~/.local/share/kicad/8.0/symbols/"),
+            os.path.expanduser("~/.config/kicad/8.0/symbols/"),
+        ]
+
+        for search_path in search_paths:
+            if os.path.exists(search_path):
+                for lib_file in os.listdir(search_path):
+                    if lib_file.endswith('.kicad_sym'):
+                        self.library_paths.append(os.path.join(search_path, lib_file))
+
+    def index_symbols(self):
+        """Parse all libraries and build symbol index"""
+        for lib_path in self.library_paths:
+            lib_name = os.path.basename(lib_path).replace('.kicad_sym', '')
+            symbols = self._parse_library(lib_path)
+
+            for symbol_name in symbols:
+                full_name = f"{lib_name}:{symbol_name}"
+                self.symbol_index[full_name] = {
+                    'library': lib_name,
+                    'library_path': lib_path,
+                    'symbol_name': symbol_name
+                }
+
+    def _parse_library(self, lib_path):
+        """Parse .kicad_sym file and extract symbol names"""
+        # Use sexpdata (already a dependency of kicad-skip)
+        import sexpdata
+
+        with open(lib_path, 'r') as f:
+            data = sexpdata.load(f)
+
+        symbols = []
+        for item in data[2:]:  # Skip header
+            if isinstance(item, list) and item[0] == Symbol('symbol'):
+                symbol_name = item[1]  # e.g., "Device:R"
+                # Extract just the symbol part after ':'
+                if ':' in symbol_name:
+                    symbol_name = symbol_name.split(':')[1]
+                symbols.append(symbol_name)
+
+        return symbols
+```
+
+### Phase 2: Dynamic Symbol Injection
+
+**Goal:** Load symbol definition from library file and inject into schematic
+
+**Challenge:** kicad-skip works with loaded schematics, but we need to dynamically add symbols to the `lib_symbols` section.
+
+**Solution:** Modify the schematic's S-expression data directly before loading with kicad-skip:
+
+```python
+def inject_symbol_into_schematic(schematic_path, library_path, symbol_name):
+    """
+    1. Read schematic S-expression
+    2. Read library S-expression
+    3. Extract symbol definition from library
+    4. Inject into schematic's lib_symbols section
+    5. Save modified schematic
+    6. Reload with kicad-skip
+    """
+    import sexpdata
+
+    # Load schematic
+    with open(schematic_path, 'r') as f:
+        sch_data = sexpdata.load(f)
+
+    # Load library
+    with open(library_path, 'r') as f:
+        lib_data = sexpdata.load(f)
+
+    # Find symbol definition in library
+    symbol_def = None
+    for item in lib_data[2:]:
+        if isinstance(item, list) and item[0] == Symbol('symbol'):
+            if symbol_name in str(item[1]):
+                symbol_def = item
+                break
+
+    if not symbol_def:
+        raise ValueError(f"Symbol {symbol_name} not found in {library_path}")
+
+    # Find lib_symbols section in schematic
+    lib_symbols_index = None
+    for i, item in enumerate(sch_data):
+        if isinstance(item, list) and item[0] == Symbol('lib_symbols'):
+            lib_symbols_index = i
+            break
+
+    # Inject symbol definition
+    if lib_symbols_index:
+        sch_data[lib_symbols_index].append(symbol_def)
+
+    # Save modified schematic
+    with open(schematic_path, 'w') as f:
+        sexpdata.dump(sch_data, f)
+
+    # Reload with kicad-skip
+    return Schematic(schematic_path)
+```
+
+### Phase 3: Template Instance Creation
+
+**Goal:** Create offscreen template instances that can be cloned
+
+**After injection:** Symbol definition is in `lib_symbols`, but we need an instance to clone from:
+
+```python
+def create_template_instance(schematic, library_name, symbol_name):
+    """
+    Create an offscreen template instance that can be cloned
+    Similar to our current _TEMPLATE_R approach
+    """
+    # This requires directly manipulating the S-expression
+    # Add a symbol instance at offscreen position with special reference
+
+    template_ref = f"_TEMPLATE_{library_name}_{symbol_name}"
+
+    # Create symbol instance (S-expression)
+    symbol_instance = [
+        Symbol('symbol'),
+        [Symbol('lib_id'), f"{library_name}:{symbol_name}"],
+        [Symbol('at'), -100, -100 - (len(schematic.symbol) * 10), 0],
+        [Symbol('unit'), 1],
+        [Symbol('in_bom'), Symbol('no')],
+        [Symbol('on_board'), Symbol('no')],
+        [Symbol('dnp'), Symbol('yes')],
+        [Symbol('uuid'), str(uuid.uuid4())],
+        [Symbol('property'), "Reference", template_ref, ...],
+        # ... more properties
+    ]
+
+    # Inject into schematic and reload
+    # ... (similar to inject_symbol_into_schematic)
+
+    return template_ref
+```
+
+### Phase 4: User-Facing API
+
+**Goal:** Simple interface for users to add any KiCad symbol
+
+**New MCP Tool: `add_schematic_component_dynamic`**
+
+```python
+def add_schematic_component_dynamic(params):
+    """
+    Add component by library:symbol notation
+
+    Example:
+    {
+        "library": "Device",
+        "symbol": "R",
+        "reference": "R1",
+        "value": "10k",
+        "x": 100,
+        "y": 100
+    }
+
+    OR using full notation:
+    {
+        "lib_symbol": "Device:R",  # Full notation
+        "reference": "R1",
+        ...
+    }
+    """
+    lib_symbol = params.get('lib_symbol') or f"{params['library']}:{params['symbol']}"
+
+    # 1. Check if symbol is already in schematic's lib_symbols
+    # 2. If not, inject it from library file
+    # 3. Create template instance if needed
+    # 4. Clone template and set properties
+
+    return {"success": True, "reference": params['reference']}
+```
+
+---
+
+## Advantages Over Template Approach
+
+### ✅ Unlimited Symbol Access
+- Access to ~10,000+ standard KiCad symbols
+- Support for custom user libraries
+- Support for 3rd-party libraries (JLCPCB, Espressif, etc.)
+
+### ✅ No Maintenance Required
+- Template doesn't need updates for new component types
+- Automatically supports new KiCad library additions
+- Works with custom symbol libraries
+
+### ✅ Better User Experience
+```
+User: "Add an STM32F103C8T6 microcontroller at position 100,100"
+AI: *Searches symbol index*
+    *Finds MCU_ST_STM32F1:STM32F103C8Tx*
+    *Loads from library*
+    *Injects into schematic*
+    *Places component*
+    ✓ Done!
+```
+
+### ✅ Flexible Symbol Search
+```python
+# Find all resistors
+symbols = lib_manager.search_symbols(query="resistor")
+# Returns: ["Device:R", "Device:R_Small", "Device:R_Network", ...]
+
+# Find all STM32 MCUs
+symbols = lib_manager.search_symbols(query="STM32", library="MCU_ST_STM32F1")
+```
+
+---
+
+## Challenges & Mitigations
+
+### Challenge 1: S-expression Manipulation Complexity
+
+**Problem:** Directly manipulating S-expression data is error-prone
+
+**Mitigation:**
+- Use `sexpdata` library (already a dependency)
+- Create helper functions for common operations
+- Add comprehensive validation and error handling
+- Extensive testing with various symbol types
+
+### Challenge 2: Performance
+
+**Problem:** Loading/reloading schematics after injection could be slow
+
+**Mitigation:**
+- **Cache loaded symbols**: Once injected, symbol stays in schematic
+- **Batch injection**: Inject multiple symbols at once
+- **Lazy loading**: Only inject symbols when first used
+
+### Challenge 3: Symbol Compatibility
+
+**Problem:** Some symbols may have complex pin configurations or multiple units
+
+**Mitigation:**
+- Start with simple 2-pin passives (R, C, L)
+- Gradually add support for multi-pin ICs
+- Handle multi-unit symbols (gates, OpAmp sections) explicitly
+- Document supported symbol types
+
+### Challenge 4: Library Version Compatibility
+
+**Problem:** KiCad symbol format may change between versions
+
+**Mitigation:**
+- Parse KiCad version from library files
+- Version-specific handling if needed
+- Fallback to template approach for unsupported formats
+
+---

+
+---
+
+## Migration Strategy
+
+### Backward Compatibility
+
+Keep template-based approach as fallback:
+
+```python
+def add_schematic_component(params):
+    """Smart component addition with fallback"""
+    # Try dynamic loading first
+    try:
+        if 'library' in params or 'lib_symbol' in params:
+            return add_schematic_component_dynamic(params)
+    except Exception as e:
+        logger.warning(f"Dynamic loading failed: {e}, falling back to template")
+
+    # Fallback to template-based
+    return add_schematic_component_template(params)
+```
+
+### Gradual Rollout
+
+1. **Week 1-2:** Implement basic dynamic loading
+2. **Week 3-4:** Test with power users, gather feedback
+3. **Week 5-6:** Make dynamic loading the default
+4. **Week 7+:** Deprecate template-only approach (keep as fallback)
+
+---
+
+## Success Criteria
+
+### Must Have
+- [ ] Load symbols from Device.kicad_sym (passives)
+- [ ] Support R, C, L, D, LED (5 core types)
+- [ ] Cross-platform library discovery
+- [ ] Proper error handling
+
+### Should Have
+- [ ] Support for all Device.kicad_sym symbols (~50 symbols)
+- [ ] Support for Connector.kicad_sym symbols
+- [ ] Symbol search by name/keyword
+- [ ] Performance: < 1 second per symbol injection
+
+### Nice to Have
+- [ ] Support for all standard libraries (~10,000 symbols)
+- [ ] Multi-unit symbol support
+- [ ] Custom library registration
+- [ ] Symbol preview/documentation
+
+---
+
+## Risk Assessment
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|------------|
+| S-expression parsing complexity | High | High | Use proven `sexpdata` library, extensive testing |
+| Performance degradation | Medium | Medium | Implement caching, lazy loading |
+| KiCad version incompatibility | Low | High | Version detection, format validation |
+| Template fallback breaks | Low | Medium | Maintain template approach in parallel |
+| User confusion | Medium | Low | Clear documentation, gradual rollout |
+
+---
+
+## Conclusion
+
+Dynamic library loading is **feasible and highly beneficial** for the schematic workflow. While the template-based approach (Option 1) provides immediate value with 13 component types, Option 2 would:
+
+1. **Eliminate the 13-component limitation**
+2. **Provide access to 10,000+ KiCad symbols**
+3. **Remove manual template maintenance**
+4. **Enable true "natural language PCB design"**
+
+**Recommendation:**
+- ✅ **Keep Option 1 (expanded template) for immediate use**
+- ✅ **Implement Option 2 (dynamic loading) over 6-8 weeks**
+- ✅ **Maintain template fallback for compatibility**
+
+This gives users immediate value while we build the robust long-term solution.
