get_pin_net was a superset of get_wire_connections with the same
coordinate-based flood-fill but two extra response fields (net, query_point)
and a reference+pin input mode. Having both tools confused LLM tool selection.
get_wire_connections now:
- Returns net (label name or null) and query_point in all response paths
- Accepts reference+pin input in addition to x/y coordinates,
resolving the pin endpoint via PinLocator internally
get_pin_net tool, handler, schema, TS registration, and tests removed.
test_wire_connectivity.py updated with coverage for all new behaviour.
