Fix Navidrome automatic library scan schedule (#101)

## Summary
- Fix env var name from `ND_SCANSCHEDULE` to `ND_SCANNER_SCHEDULE` (Navidrome uses viper config where dots become underscores)
- Use explicit `@every 1h` format for clarity
- Reorder CLAUDE.md rules to emphasize running zk-docs first

## Root Cause
Navidrome logs showed "Periodic scan is DISABLED" at startup despite the env var being set. The config key is `scanner.schedule`, which translates to `ND_SCANNER_SCHEDULE` (not `ND_SCANSCHEDULE`).

## Deployment and Testing
- [ ] Sync navidrome app: `argocd app sync navidrome`
- [ ] Verify pod restarts with new env var
- [ ] Check logs for "Scheduling scanner" message instead of "Periodic scan is DISABLED"
- [ ] Wait ~1 hour and confirm scan runs automatically

 3. **Feature branches only** - checkout main, pull, create branch, commit often
 4. **Create PRs via `tea pr create`** - user reviews before deploy, merges after
 5. **Check PR comments with `mise run pr-comments <pr_number>`** before proceeding
 6. **Add changelog fragments** - `docs/changelog.d/<branch>.<type>.md`
-   Types: `feature`, `bugfix`, `infra`, `doc`, `ai`, `misc`

 9. **Never merge PRs or push to main without explicit request**
