WP-0001-T008: operator docs + ADR cross-linking; mark WP-0001 done

docs/OPERATOR.md (new): runbook with prerequisites, quick start,
environment variables, SQLite + PostgreSQL setup, storage layout,
CLI reference, HTTP /health reference, an end-to-end Python smoke
test (create_package -> ingest_file -> finalize -> manifest), the
replay / disaster-recovery procedure, common failure modes, and a
References section that links every ADR (0001..0006), the
blueprint, platform ambition, roadmap, and assembly experiment.

README.md: refreshed to v0.1 baseline status. Quick-start uses the
real flow (uv sync, migrate-fresh, dev, /health, artifactstore health).
Make targets and CLI commands tabulated. Links docs/OPERATOR.md.

AGENTS.md: Current Repo Shape now reflects the landed scaffold +
library + CLI + HTTP app rather than "no runnable scaffold yet";
links OPERATOR.md and lists the canonical local commands.

workplans/ARTIFACT-STORE-WP-0001-service-baseline.md:
- T008 marked done.
- frontmatter status: active -> done; updated: 2026-05-16.

All ten WP-0001 tasks are now done (T001/T002/T003/T008/T009/T010/
T011/T012/T013/T014). Foundation workplan retires.

Gates: ruff clean, mypy --strict clean, 83 tests pass.

-Requires Python ≥ 3.12 and [`uv`](https://docs.astral.sh/uv/) on the path.
+Requires Python ≥ 3.12 and [`uv`](https://docs.astral.sh/uv/).
 
 ```sh
-make install        # uv sync --all-extras
-cp .env.example .env
+uv sync --all-extras          # install dependencies (creates .venv + uv.lock)
+cp .env.example .env          # optional; defaults work out of the box
 
-make dev            # uvicorn artifactstore.api.http:app --reload
-make test           # pytest
-make lint           # ruff check + ruff format --check
-make type           # mypy --strict
-make migrate        # alembic upgrade head (configured in WP-0001-T002)
+make migrate-fresh            # initialise ./var/artifactstore.db
+make dev                      # uvicorn on 127.0.0.1:8000
+
+# in another terminal
+curl -s http://127.0.0.1:8000/health | python3 -m json.tool
+artifactstore health
 ```
 
-The dev server listens on `127.0.0.1:8000`. The scaffold root route
-returns `{"service": "artifact-store", "status": "scaffold"}`; the real
-`/health` endpoint lands in `WP-0001-T014`.
+## Make targets
+
+| Target               | Purpose |
+|----------------------|---------|
+| `make install`       | `uv sync --all-extras` |
+| `make dev`           | run the FastAPI app with reload |
+| `make test`          | run the pytest suite |
+| `make lint`          | ruff check + ruff format --check |
+| `make format`        | apply ruff format + ruff check --fix |
+| `make type`          | mypy --strict |
+| `make migrate`       | `alembic upgrade head` |
+| `make migrate-fresh` | drop the local SQLite DB and re-run migrations |
+| `make clean`         | remove caches and build artefacts |
+
+## CLI
+
+```sh
+artifactstore version     # print the package version
+artifactstore migrate     # alembic upgrade head
+artifactstore replay      # rebuild materialised views from the event log
+artifactstore health      # JSON liveness summary (same payload as /health)
