auto-update.sh fetches origin every 5 minutes. If new commits are
found it pulls and selectively restarts only what changed:
- server/ or Cargo.* → rebuild + restart server container
- docker-compose.yml → full stack up -d
- proxy/Caddyfile → caddy reload
- anything else → no restart needed
start.sh now installs hiy-update.service + hiy-update.timer alongside
the existing hiy.service boot unit.
