Viktor Vaczi aa7e9634e3 Add board_model library and Phase 3 wxUniversal plan
- Add board_model library with PCB data structures (BOARD, FOOTPRINT, PAD, etc.)
- Add thirdparty include paths (fmt, nlohmann_json, magic_enum, dynamic_bitset)
- Enable wxRegex support in wxBase build (builtin PCRE2)
- Add wxregex imported library to CMakeLists.txt
- Add Phase 3 implementation plan for wxWidgets wxUniversal WASM port

The board_model target includes:
- Common infrastructure (eda_item, eda_shape, eda_text, lset, kiid, etc.)
- PCB board model (board, footprint, pad, pcb_track, zone, etc.)
