- TournamentPlayer/TournamentPairing/TournamentSettings move into
serverinfo_tournament.proto, imported by both the tournament event and
the tournament game commands, so Command_CreateGame reaches them without
crossing the command/event boundary
- Command_CreateGame carries the full TournamentSettings instead of a
duplicate games_per_match field, keeping game creation and mid-game
changes on one wire representation
- draw results are explicit: Command_ReportMatchResult and
TournamentPairing gain is_draw, so a report stays distinguishable from
an unset -1 winner
- pairing match-wins are uint32 like the other game counts
Adds the protocol layer for the tournament game mode:
- Event_TournamentState (2027) carrying phase, round counters, player
standings, pairings, and settings (games_per_match)
- Command_ReportMatchResult / Command_AdvanceTournament /
Command_TournamentSettingsSelect game command extensions (1037-1039)
- is_tournament flag on Command_CreateGame and ServerInfo_Game;
is_tournament and parent_game_id on Event_GameStateChanged
