What's changed
- route: periodically clean stale buildbox folders (#23) — adds a background goroutine that sweeps
public/buildboxhourly and removes build folders older than one year, reclaiming disk space on the deployment. Only UUID-named directories are pruned (bookkeeping files are left untouched), with guards against accidental recursive deletes on the mounted data volume. Closes #21.
