Bootstrap a new FastAPI service with uv + the canonical strict baseline — Ruff with curated extend-select, mypy strict with extra error codes, pytest baseline. Installs the latest FastAPI, sets up a Pydantic Settings module with sensible API defaults, scaffolds a `/healthz` endpoint with its smoke test. Asks the user the Python version and whether to use SQLModel, SQLAlchemy 2.x, or no ORM. **Deliberately skips database driver installation** — pick yours and add it once the connection string is set. Use whenever the user asks to "create / initialize / scaffold / bootstrap / start" a FastAPI project, service, API, or backend.
