fix: rename check_wire_collisions to find_wires_crossing_symbols and detect pass-through wires

Browse Source 
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.
