James Pine 219cfb1605 docs: update PROJECT_STATUS.md to reflect multi-engine architecture
- Reflects merged PRs: #254 (LuxTTS/multi-engine), #257 (Chatterbox), #252 (CUDA swap), #238 (download UI)
- Updated architecture diagram to show all 4 TTS engines
- Added TTS engine comparison table and multi-engine architecture section
- Marked resolved bottlenecks (singleton backend, frontend Qwen assumptions)
- Updated PR triage: marked #194 and #33 as superseded
- Added 'Adding a New Engine' guide (now ~1 day effort)
- Updated recommended priorities to reflect current state
- Added new API endpoints (CUDA, cancel, active tasks)

James Pine 2867421550 feat: CUDA backend swap via binary download and restart
Add the ability to download a CUDA-enabled backend binary (~2.4 GB) and
swap it in via a backend-only restart, solving the #1 user pain point
(19 open 'GPU not detected' issues caused by GitHub's 2 GB asset limit).

Backend:
- cuda_download.py: download from R2 (primary) or GitHub split-parts
  (fallback), SHA-256 verification, atomic writes, progress via SSE
- 4 new endpoints: GET/POST/DELETE /backend/cuda-*, GET cuda-progress
- server.py: --version flag, auto-detect variant from binary name
- build_binary.py: --cuda flag for CUDA PyInstaller builds
- split_binary.py: split large binaries into <2GB GitHub Release assets
- CI workflow for building CUDA binary

Tauri:
- restart_server command (stop -> wait -> start)
- start_server prefers CUDA binary from {data_dir}/backends/ if present
- Version mismatch check: runs --version before launching CUDA binary

Frontend:
- GpuAcceleration component: download, progress, restart, switch, delete
- API client + types for CUDA status and management
- Platform lifecycle: restartServer() on Tauri/Web
- Aggressive 1s health polling during restart for fast reconnection
