Summary

This PR expands the Pomodoro break minigame experience with multiple playable game modes, champion visibility, and stricter leaderboard submission rules. It also modularizes game UI into dedicated components for maintainability and improves draw-tracking accuracy for the circle game. Alongside feature delivery, test fixtures and page/action tests were updated to align with the latest schema and timer page data requirements.

Changes

• Added new break minigames: Shakespeare typing sprint, circle draw accuracy game, and cursor survivor.
• Kept and integrated existing minigames (aim, dino, bricks, flappy arrow) under a unified selector.
• Refactored minigame rendering into modular components under a dedicated minigames folder.
• Added shared minigame config/types modules and wired timer client to consume them.
• Updated score submission logic to submit only when a score beats the player’s best of the day or all-time best.
• Added champion snapshot support and champion display per game in the break minigame card.
• Improved circle draw fidelity with pointer events, pointer capture, and interpolated point sampling.
• Updated timer page data loading to include champion snapshot data.
• Updated action tests for new leaderboard submission semantics.
• Updated admin members test fixture to include required pomodoro preference fields after schema evolution.
• Updated README badges/logo/links and removed outdated feature-set references.

How to Test

1. Run pnpm lint, pnpm typecheck, and pnpm build.
2. Run pnpm test:ci (or focused suites) and verify all tests pass.
3. Launch the app, open the timer page, enter a break, and verify:
   • You can select/play each minigame.
   • Circle draw follows cursor smoothly.
   • Score is submitted only when beating daily/all-time best.
   • Champion list updates for the relevant game after qualifying submissions.

Notes for Reviewer

Please pay special attention to the leaderboard semantics change:

• allTimeScore now behaves as best-ever score for ranking.
• bestScore is treated as best score for the current day (reset behavior is date-driven via updatedAt in action logic).

Follow-up suggestion:

• If desired, we can make daily-best explicit in schema with a dedicated dailyBestScore + dailyBestDate for clearer long-term semantics and reporting.
