- Implement rpc_find_match Nakama RPC function - Search for existing authoritative TicTacToe matches via MatchList - Return first match with available slot (size < 2) - Create new match using MatchCreate when none available - Add request/response structs for future extensibility - Log match search, selection, and creation flow - Gracefully handle optional JSON payload and invalid input
