The WinnerID field is a player-slot integer as string (e.g. "2"), not a bot_id.
The SQL query already computes the correct winner status in p.Won field.
Fixed in 3 functions:
- matchToSummary: Changed Won: p.BotID == m.WinnerID to Won: p.Won
- buildPlaylistMatch: Changed Won: p.BotID == m.WinnerID to Won: p.Won
- ratingUpsetMagnitude: Use p.Won to identify winner instead of comparing with m.WinnerID
- maxScoreDiff: Use p.Won to identify winner instead of comparing with m.WinnerID
- isEvolutionBreakthrough: Find winner using p.Won before checking if evolved
This fixes the issue where 984/1000 prod matches had winner_id set but all participants showed won: false.
