Update README and CLAUDE.md: Watchtower as recommended install method

README:
- Replace vague Updates section with a full Watchtower compose snippet
  as the recommended auto-update approach for homelab users — no SSH,
  no manual pulls, updates within 5 minutes of a release automatically.
- Update TrueNAS compose snippet to include Watchtower alongside the app.
- Keep manual docker compose pull fallback for users who prefer control.

CLAUDE.md:
- Clarify that backend/static/ is gitignored and built inside the Docker
  image from source — never commit files under that path.
- Update TrueNAS environment note: Watchtower handles updates, images
  land on GHCR within ~1 min of a master push, Watchtower pulls within 5.

 The `docker-compose.yml` mounts `./data` as a volume, so your `config.json`, `channels.json`, and `plex_library.csv` persist between runs. To pick up code changes, rebuild: `docker compose build && docker compose up`.
 
+Note: `backend/static/` is **gitignored** — the Dockerfile builds the frontend from source inside the container (`npm run build` runs during `docker build`). Never commit files under `backend/static/`.

 Two environments:
 - **localhost:7979** — local Docker build for testing before pushing
-- **TrueNAS** — production, pulls image from GHCR automatically on every `master` push via GitHub Actions
+- **TrueNAS** — production, runs `ghcr.io/alpinearchitecture/programmarr:latest` with Watchtower for automatic updates. New images land on GHCR within ~1 min of a master push; Watchtower picks them up within 5 min.

 ### Updates
 
-The image is rebuilt and pushed automatically on every commit. To update:
+Add [Watchtower](https://containrrr.dev/watchtower/) to your compose file and updates happen automatically — no SSH, no manual pulls, no Portainer. Watchtower checks every 5 minutes and restarts the container if a new image is available:
+
+```yaml
+services:
+  programmarr:
+    image: ghcr.io/alpinearchitecture/programmarr:latest
+    container_name: programmarr

 docker compose pull && docker compose up -d
