merge: upstream/main (57 commits) — preserve PR #102 net label fix
Merged upstream/main into our fork. Conflict in connection_schematic.py
resolved by taking upstream's file and re-applying our fix:
- all_match_points = connected_wire_points | label positions
- Allows nets where labels are placed directly at pin endpoints (no wire)
Upstream changes include: security fixes (8 vulns), new schematic tools
(get_net_at_point, find_orphaned_wires, snap_to_grid, get_wire_connections),
generate_netlist rewrite via kicad-cli, wire preservation on component move,
schematic analysis tools, KiCad 10 support.
