feat(ebook): add Docker packaging and lifecycle tooling

Add a self-contained docker/ package for running the ebook search app
against the existing Postgres database on jeeves:

- Dockerfile: python:3.14-slim image, non-root user, runs the FastAPI
  app on port 8070
- docker-compose.yml: service definition with library volume mount,
  BM25 index volume, .env loading, and a /health healthcheck
- containers.py: Typer CLI (ebook-search-containers) for build/start/
  stop/restart/logs/ps lifecycle management
- README.md: usage and configuration docs

+# Ebook Search Docker
+
+Run the EPUB search app against the existing Postgres database on `jeeves`:
+
+```sh
+ebook-search-containers start --library-path /path/to/epubs --build
+```
+
+All ebook-search Docker files live in this directory:
+
+- `Dockerfile`
+- `docker-compose.yml`
+- `containers.py`
+- `container.py`
+
+The app listens on `http://localhost:8070`.
+
+Useful lifecycle commands:
+
+```sh
+ebook-search-containers build
+ebook-search-containers start --library-path /path/to/epubs
+ebook-search-containers logs
+ebook-search-containers ps
+ebook-search-containers stop
+```
+
+Direct compose usage from the repo root:
+
+```sh
+docker compose -f python/ebook_search/docker/docker-compose.yml ps
+```
+
+The compose service also loads the repo root `.env` into the container via `env_file`.
+
+Mount your EPUB directory by setting `EBOOK_LIBRARY_HOST_PATH` in an env file or on the command line. The container sees it as `/library`, and `EBOOK_SEARCH_LIBRARY_PATHS` is set to `/library` inside the container.
+
+Database connection settings are controlled by `RICHIE_DB`, `RICHIE_HOST`, `RICHIE_PORT`, `RICHIE_USER`, and `RICHIE_PASSWORD`. The default host is `jeeves`.
+
+Startup runs the Richie Alembic migrations automatically after creating the `main` schema and `vector` extension.
