Function useBuzzer

useBuzzer(game: Game, questionId: string | null): UseBuzzerResult
All buzzer logic for the GM side.
Parameters
- game: Game
  The active game record. Used for configuration flags and IDs.
- questionId: string | null
  ID of the currently displayed question, or null if none.
Returns UseBuzzerResult
Remarks
This hook does not subscribe to transport events itself — the caller is responsible for forwarding BUZZ events via handleIncomingBuzz. This keeps the single transport subscription in the GameMaster component and avoids duplicate registrations when the hook re-renders.

False-start handling: If game.allowFalseStarts is false, buzzes that arrive while the buzzer is locked are silently ignored. If true, they are recorded with isFalseStart: true and shown in the GM's buzz list.

Auto-lock: When game.autoLockOnFirstCorrect is true, the buzzer is locked automatically after the GM rules a buzz as 'Correct'.

Scoring: When game.scoringEnabled is true, a correct ruling increments the player's score by the difficulty point value of the current question.
Example
```
const { displayBuzzes, toggleLock, adjudicate } = useBuzzer(game, currentQuestionId)

useTransportEvents(useCallback(event => {
  if (event.type === 'BUZZ') {
    handleIncomingBuzz(event)
  }
}, [handleIncomingBuzz]))
```
