KiCad's native ERC already checks for unconnected pins with better
accuracy (hierarchical sheets, bus connections, custom rules). Remove
the reimplemented version and its dead helper _parse_no_connects.

Eliminate repeated file parsing by extracting _extract_lib_symbols helper
that walks already-parsed sexp_data once instead of re-reading the file
per symbol via PinLocator. Support diagonal wire overlap detection using
cross-product parallelism and 1D projection. Fix wire region inclusion to
use AABB intersection for pass-through wires. Normalize view region
coordinates. Clarify tolerance docstrings across Python, TS, and schema.

Wires that start at a component pin but continue through the body were
incorrectly suppressed as "valid connections." Now nudges the pin endpoint
toward the other end and re-tests intersection — if the shortened segment
still hits the bbox, the wire passes through and is flagged.
Renamed the tool from check_wire_collisions to find_wires_crossing_symbols
across all layers (Python, handler, schema, TypeScript) to clarify that it
finds wires crossing over component symbols, which is unacceptable in
schematics.

Add five new read-only schematic analysis MCP tools:
- get_schematic_view_region: export cropped schematic region as PNG/SVG
- find_unconnected_pins: list pins with no wire/label/power connection
- find_overlapping_elements: detect duplicate symbols, stacked labels, collinear wire overlaps
- get_elements_in_region: list all symbols/wires/labels in a bounding box
- check_wire_collisions: detect wires passing through component bodies
Includes Python handler dispatch, tool schemas, TypeScript server bindings,
the schematic_analysis command module, and a full test suite (28 tests passing).

- add_schematic_net_label: warn in description that coords must be exact pin endpoints; recommend connect_to_net instead
- connect_to_net: stub wire direction now follows pin angle (was hardcoded +X)
- pin_locator.py: add get_pin_angle() and _get_lib_id() helpers
- new tool: get_schematic_pin_locations(schematicPath, reference) → returns exact x/y of every pin endpoint, so Claude can place labels correctly
Implements advanced trace manipulation and routing pattern copying:
- Enhanced delete_trace with net-based bulk deletion and layer filtering
- Added modify_trace to change width, layer, or net by UUID/position
- Added copy_routing_pattern to replicate routing between component groups

Issue #32 - Unknown command errors:
- Register get_board_extents in command_routes (was implemented but not registered)
- Implement find_component command with pattern matching on reference/value/footprint
- Add schemas for both commands
Issue #30 - PCB routing replication (Phase 1):
- Implement get_component_pads: returns all pads with positions, nets, shapes
- Implement get_pad_position: returns specific pad coordinates and properties
- Implement query_traces: query traces by net, layer, or bounding box
- Add schemas for all new commands
Issue #26 - Schematic workflow:
- Add missing schemas for add_schematic_connection, add_schematic_net_label,
connect_to_net, get_net_connections, and generate_netlist
Issue #19 - macOS Python path detection:
- Add Python 3.13 to version detection
- Add alternative KiCAD installation paths (user Applications, capitalization variants)
- Add Homebrew Python fallback paths for Apple Silicon and Intel Macs
- Expand platform_helper.py with same improvements
