feat(04-01): run game canonicalization pipeline

Generate canonical games with team/stadium links for 5760 games across
NBA, MLB, NHL, NFL, and MLS.

Added missing team aliases:
- NFL WSH -> team_nfl_was (Washington Commanders)
- MLS NY -> team_mls_nyrb (NY Red Bulls)
- MLS ATX -> team_mls_aus (Austin FC)

Remaining 8 warnings are expected NFL playoff placeholders (TBD/AFC/NFC).
