feat(p1): scaffolding + Device Manager / VRAM probe + CLI detect
- pyproject (uv, src layout) + extras: engine/gpu/api/diarize/llm
- config.py (pydantic-settings, SCRIBE_ env)
- devices/: vram_probe (NVML/psutil/disk) + DeviceManager →
capability tier T0–T3, precision by cc/VRAM, worker estimate (계획 §3.6, AC-2/3)
- cli.py (typer): detect (구현) + transcribe/bench/serve (스텁)
- run.sh, .env.example, README
Verified on GTX 1050/2GB: detect → T0_CPU (turbo doesn't fit → explicit
downgrade, fail-explicit). Overrides (--device/--workers) work. 7 unit tests
cover T0–T3 + overrides via synthetic VRAM. ruff clean.
