Game Completion

Add proper game completion signaling so Puzzmo knows when the player has finished.

Steps

1. Find the game's win condition / completion check.

2. When the game is won, call sdk.gameCompleted() with gameplay metrics:

   sdk.gameCompleted({
     pointsAwarded: calculateScore(),
     elapsedTimeSecs: sdk.timer.timeSecs(),
     additionalTimeAddedSecs: sdk.timer.addedTimeSecs(),
     hintsUsed: hintsUsed,
     resetsUsed: 0,
     metric1: 0,
     metric2: 0,
     metric3: 0,
     metric4: 0,
     metricStrings: [],
     cheatsUsed: 0,
   })
   

3. After any victory animation completes, call sdk.showCompletionScreen():

   sdk.showCompletionScreen(
     [{ type: "md", text: "**Congratulations!** You solved the puzzle!" }],
     gameplayData,
     true, // showRetry
   )
   

4. Make sure gameCompleted is called BEFORE showCompletionScreen. The host processes the completion data first, then displays the completion UI.

5. The timer automatically stops when gameCompleted is called - you don't need to stop it manually.

Success Criteria

• npm run build completes without errors
• When the game is won, gameCompleted fires with score data
• After victory animation, showCompletionScreen fires
• The completion flow works: play -> win -> gameCompleted -> animation -> showCompletionScreen
