Krzysztof kuhy Rudnicki 5a9296d8aa Add bucket_catch: osu!catch browser game with 100% frontend test coverage
Frontend (React 19 + Vite 6 + TypeScript strict):
- DropZone, ModeSelect, GameCanvas, PuzzleCanvas, ScoreScreen, PuzzleResult
- File-drop game with AABB collision; download (JSZip) and upload (NestJS) modes
- Puzzle mode: NxN image slice via OffscreenCanvas; Union-Find spatial clustering
  guarantees 100% catch rate is always achievable regardless of piece speeds
- ESLint typescript-eslint strict-type-checked (zero errors)
- 145 Vitest tests; 100% coverage on statements/branches/functions/lines

Backend (NestJS 11):
- POST /files/upload (multer disk storage) and GET /health

"objective": "Add bucket_catch to testsAndMisc — a browser game where falling files/puzzle pieces are caught with a mouse-tracked basket. The frontend (React 19 + Vite 6 + TypeScript strict) achieves 100% Vitest coverage across statements, branches, functions, and lines. The backend (NestJS 11) exposes file upload and health endpoints.",

"Puzzle mode guarantees 100% catchable via Union-Find spatial clustering"
