Answers "what net is pin X of component Y on?" without requiring
callers to triangulate from list_schematic_nets or know a wire
coordinate first.
Accepts either {reference, pin} (resolved via PinLocator) or {x, y}
coordinate. Returns net label name (or null for unnamed nets), all
connected pins, wire segments, and the resolved query point.

Add type annotations to all previously untyped functions and remove 9
suppressed error codes (call-arg, assignment, return-value, operator,
has-type, dict-item, misc, list-item, annotation-unchecked) by fixing
the underlying type issues.
Add [[tool.mypy.overrides]] with ignore_missing_imports for KiCAD-specific
modules (pcbnew, sexpdata, skip, cairosvg, kipy, PIL) so the pre-commit
mypy hook passes in its isolated venv. Add types-requests and pytest to
additional_dependencies in .pre-commit-config.yaml.
Also fixes several real bugs uncovered by stricter checks: incorrect static
calls to instance methods in swig_backend, wrong return type on get_size,
missing value param in BoardAPI.place_component, variable shadowing in
kicad_process.py, unqualified LibraryManager reference in kicad_interface,
and missing top-level Path import.

Add isort configuration (profile=black, line_length=100) to pyproject.toml,
add isort pre-commit hook, and auto-sort imports across all Python source files.

Add [tool.black] config to pyproject.toml and Black hook to
.pre-commit-config.yaml (rev 26.3.1), then auto-format all Python
source and test files with line-length=100, target-version=py310.

Remove the 0.5mm query tolerance in favour of exact integer-unit matching
on all coordinate lookups (seed, label bridging, pin matching), mirroring
KiCad's own connectivity algorithm. Callers must supply exact wire endpoint
coordinates (e.g. from list_schematic_wires).

Update tool description and Python docstring to make clear that the
query point must be at a wire endpoint or junction — midpoints of
wire segments are not matched.

Shared-endpoint adjacency already connects all wires meeting at the same
point, making explicit junction handling a no-op duplicate.

Move wire connectivity logic from _handle_get_wire_connections into
commands/wire_connectivity.py. Use KiCad's internal integer unit system
(10,000 IU/mm) with exact coordinate matching instead of tolerance-based
float comparison, mirroring how KiCad itself determines connectivity.
Key improvements:
- Exact integer matching for wire endpoints (O(1) dict lookup vs O(n) grid scan)
- Junction support for T-connections
- Multi-unit symbol support (removed incorrect processed_refs dedup)
- Single public API: get_wire_connections()
