docs: Update README with dynamic symbol loading breakthrough

Updated README.md to highlight the major dynamic loading feature:

✅ Updated 'What's New' section
- Added Phase 2: Dynamic Symbol Loading breakthrough
- Documented access to all ~10,000 KiCad symbols
- Added technical architecture explanation
- Example usage with STM32 microcontroller

✅ Updated Schematic Design tools section
- Changed from 'template-based' to 'dynamic loading'
- Explained automatic library search and injection
- Noted fallback to 13 static templates

✅ Updated Project Status
- Added 'DYNAMIC SYMBOL LOADING' as key feature
- Highlighted access to full KiCad symbol libraries
- Noted automatic dynamic injection capability

This brings the README in line with the breakthrough achieved in
commits 1d9e92a and 148f3ef.

-### Critical Schematic Workflow Fix (Issue #26 Resolved)
+### 🚀 Critical Schematic Workflow Fix + Dynamic Symbol Loading (Issue #26)
-The schematic workflow was completely broken in previous versions - **this is now fixed!**
+The schematic workflow was completely broken in previous versions - **this is now fixed AND dramatically enhanced!**
 
 **What was broken:**
 - `create_project` only created PCB files, no schematics
 - `add_schematic_component` called non-existent API methods
 - Schematics couldn't be created or edited at all
+- Only 13 component types available (severe limitation)
 
 **How we fixed it:**
-- Implemented template-based symbol cloning approach (kicad-skip limitation workaround)
+1. **Phase 1:** Template-based symbol cloning approach
-- `create_project` now creates both .kicad_pcb and .kicad_sch files
+   - `create_project` now creates both .kicad_pcb and .kicad_sch files
-- Added pre-configured template schematics with cloneable R, C, LED symbols
+   - Added pre-configured template schematics with 13 common component types
-- Rewrote component placement to use proper `clone()` API
+   - Rewrote component placement to use proper `clone()` API
-- Full end-to-end schematic workflow now functional
 
-**Technical Details:**
+2. **Phase 2:** Dynamic Symbol Loading (BREAKTHROUGH!) 🎉
-The kicad-skip library cannot create symbols from scratch - it can only clone existing symbols from loaded schematics. We solved this by creating template schematic files (`python/templates/`) with pre-configured symbols that can be cloned and modified.
+   - **Access to ALL ~10,000 KiCad symbols** from standard libraries!
+   - Automatic detection and dynamic loading from `.kicad_sym` library files
+   - Zero configuration required - just specify library and symbol name
+   - Seamless integration with existing MCP tools
+   - Full S-expression parsing and injection system
 
-See [Schematic Workflow Fix Documentation](docs/SCHEMATIC_WORKFLOW_FIX.md) for technical details.
+**Technical Architecture:**
+The kicad-skip library cannot create symbols from scratch - it can only clone existing symbols. We implemented a two-phase solution:
+
+1. **Static Templates:** 13 pre-configured symbols (R, C, L, LED, etc.) for instant use
+2. **Dynamic Loading:** On-demand injection of ANY symbol from KiCad libraries:
+   - Parse `.kicad_sym` library files using S-expression parser
+   - Inject symbol definition into schematic's `lib_symbols` section
+   - Create offscreen template instance
+   - Reload schematic so kicad-skip sees new template
+   - Clone template to create actual component
+
+**Example - Now Works with ANY Symbol:**
+```json
+{
+  "type": "STM32F103C8Tx",
+  "library": "MCU_ST_STM32F1",
+  "reference": "U1",
+  "footprint": "Package_QFP:LQFP-48_7x7mm_P0.5mm"
+}
+```
+
+See [Dynamic Loading Status](docs/DYNAMIC_LOADING_STATUS.md) for technical details and test results.
