feat: Add missing routing/component tools and fix SWIG/UUID bugs
New MCP tools added (TypeScript layer):
- Routing: delete_trace, query_traces, get_nets_list, modify_trace,
create_netclass, route_differential_pair, refill_zones (with SWIG warning)
- Component: get_component_pads, get_component_list, get_pad_position,
place_component_array, align_components, duplicate_component
Bug fixes:
- routing.py: Fix SwigPyObject UUID comparison (str() -> m_Uuid.AsString())
- routing.py: Fix SWIG iterator invalidation after board.Remove()
by converting board.Tracks() to list() before iteration
- routing.py: Add board.SetModified() and clear Python refs after Remove()
to prevent dangling SWIG pointers crashing subsequent calls
- routing.py: Wrap each track access in try/except in query_traces()
to gracefully skip invalid track objects after bulk delete
- routing.py: Add missing return statement (mypy fix)
- library.py: Fix search_footprints param mapping search_term->pattern
- library.py: Fix fp.name -> fp.full_name field access
- library.py: Accept both 'pattern' and 'search_term' parameter names
- library.py: Add library filter support in search_footprints
- library.py: Fix loop variable shadowing Path object (mypy fix)
- design_rules.py: Add type annotation for violation_counts (mypy fix)
Contribution guidelines followed (CONTRIBUTING.md):
- black python/ applied (3 touched files pass without changes)
- mypy python/ passes with 0 errors on all changed files
- npx prettier --write applied to changed TypeScript files
- npm run build passes (tsc --noEmit: 0 errors)
- Commit messages follow feat:/fix: convention
Note on diff size: The large insertion/deletion count in the changed files
is due to black and prettier reformatting previously unformatted code
(missing trailing commas, quote style, line length). The actual logic
changes are limited to the 6 files listed above.
Note: refill_zones has known SWIG segfault risk (see KNOWN_ISSUES.md).
Prefer IPC backend (KiCAD open) or zone fill via KiCAD UI.
