feat(03-02): add NWSL to canonicalization pipeline

- Import NWSL_TEAMS from nwsl module
- Add NWSL_DIVISIONS dict (single league structure, no divisions)
- Add NWSL to sport_mappings for team canonicalization
- Add NWSL team abbreviation aliases (ANG, GOTHAM, NCC, BAY, etc.)
- Add NWSL stadium aliases (CPKC Stadium, SeatGeek Stadium, WakeMed, etc.)

Total teams: 180 (13 NWSL teams added)
Final breakdown: NBA(30) + MLB(30) + NHL(32) + NFL(32) + MLS(30) + WNBA(13) + NWSL(13)
