PinLocator.get_all_symbol_pins resolves symbols by reference designator,
so when multiple components share the same unannotated reference (e.g. "Q?"),
it always returned the first match's pin positions. Every duplicate then
got an identical bounding box, causing a single wire to be flagged against
all N instances instead of only the ones it actually crosses.
Fix: add _compute_pin_positions_direct() that computes absolute pin positions
directly from each symbol's own (at x y rotation) and (mirror ...) data plus
pin definitions fetched by lib_id — no reference-name lookup involved.
Also extend _parse_symbols to capture mirror_x/mirror_y flags.
Add regression test: two "R?" at different positions, wire crossing only
one → must produce 0 collisions against the far-away component.

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).

Auto-detects runtime: Java 21+ direct or Docker/Podman fallback.
Discovers docker/podman via PATH instead of hardcoding.
README includes one-time setup with JAR download + Docker pull.
31 tests covering both execution modes.
4 new MCP tools: autoroute (full DSN→Freerouting→SES pipeline),
export_dsn, import_ses, check_freerouting. Requires Java 11+ and
freerouting.jar. Includes 21 test cases and README usage examples.
- Add python/tests/conftest.py with MagicMock stubs for pcbnew/skip
- Add python/tests/test_schematic_tools.py with 29 tests covering
WireManager.delete_wire, WireManager.delete_label (unit + integration),
and parameter validation for all 11 new _handle_* methods
- Apply black formatting to component_schematic.py, wire_manager.py,
and kicad_interface.py

The handler used a line-by-line regex requiring (symbol and (lib_id on
the same line, but KiCAD's file writer places them on separate lines.
Replace with the content-string approach (already used by edit handler)
so \s+ matches across newlines. Add regression tests covering inline,
multi-line, and power symbol (#PWR) cases.

- New `get_schematic_component` MCP tool returns component position and
all field values with their label (at x/y/angle) positions
- Extends `edit_schematic_component` with optional `fieldPositions` dict
so callers can reposition Reference/Value/etc. labels in one call
- Adds 18 tests (6 unit, 12 integration) covering parsing, round-trips,
and edge cases
