feat(pinokio): clean one-click launcher for multi-tts-server

- install: clone app source, create venv, install deps + torch + models
- start: daemon uvicorn on 127.0.0.1 with auto-captured URL
- reset: remove venv/cache/models but keep source
- update: pull both launcher and app, then re-install
- sanitized: no local env details, no TODO/DONE
- icon.png included
