feat(02-01): bootstrap Python project scaffold with all Phase 2 dependencies

- uv project configured as led-sync-studio, requires-python >= 3.11
- Dependencies declared: miniaudio==1.61, sounddevice==0.5.5, numpy>=2.4.4, pydantic==2.12.5, aubio>=0.4.9
- aubio built from source (no aarch64 wheel on PyPI)
- sounddevice installed; requires libportaudio2 on target system (Raspberry Pi OS)
- dev deps: pytest>=8.0, pytest-asyncio>=0.23
- Tests pass: led_sync importable, all deps installed
