docs(setup): add Docker/Podman stop/restart instructions

Users who installed via `./install.sh --docker` had no documented way to
restart the container after stopping it. Add clear lifecycle instructions
(stop, start, restart, logs, health check) to both the bootstrap guide and
the operations runbook, covering docker-compose, manual `docker run`, and
Podman-specific flags.

Closes #3474

+## Docker / Podman Runtime
+
+If you installed via `./install.sh --docker`, the container exits after onboarding. To run
+ZeroClaw as a long-lived container, use the repository `docker-compose.yml` or start a
+container manually against the persisted data directory.
+
+### Recommended: docker-compose
+
+```bash
+# Start (detached, auto-restarts on reboot)
+docker compose up -d
+
+# Stop
+docker compose down
+
+# Restart
+docker compose up -d
+```
+
+Replace `docker` with `podman` if using Podman.
+
+### Manual container lifecycle
+
+```bash
+# Start a new container from the bootstrap image
+docker run -d --name zeroclaw \
+  --restart unless-stopped \
+  -v "$PWD/.zeroclaw-docker/.zeroclaw:/zeroclaw-data/.zeroclaw" \
+  -v "$PWD/.zeroclaw-docker/workspace:/zeroclaw-data/workspace" \
+  -e HOME=/zeroclaw-data \
+  -e ZEROCLAW_WORKSPACE=/zeroclaw-data/workspace \
+  -p 42617:42617 \
+  zeroclaw-bootstrap:local \
+  gateway
+
+# Stop (preserves config and workspace)
+docker stop zeroclaw
+
+# Restart a stopped container
+docker start zeroclaw
+
+# View logs
+docker logs -f zeroclaw
+
+# Health check
+docker exec zeroclaw zeroclaw status
+```
+
+For Podman, add `--userns keep-id --user "$(id -u):$(id -g)"` and append `:Z` to volume mounts.
+
+### Key detail: do not re-run install.sh to restart
+
+Re-running `install.sh --docker` rebuilds the image and re-runs onboarding. To simply
+restart, use `docker start`, `docker compose up -d`, or `podman start`.
+
+For full setup instructions, see [one-click-bootstrap.md](../setup-guides/one-click-bootstrap.md#stopping-and-restarting-a-dockerpodman-container).
