- matchStatusEnum + season_matches + match_sub_games tables in schema
- externalSeasonId column on sports_seasons for API linkage
- Drizzle migration 0120_tidy_invaders.sql
- season-match model (upsert w/ onConflictDoUpdate, queries by event/season/stage)
- CS2 admin: Swiss rounds read-only section in cs2-setup + new manual swiss-matches route
- 7 unit tests for model (upsert conflict, null stage/round for non-CS2 sports, bulk, sub-games)
