perf: skip initial patrol if one ran recently

When the service restarts, it now checks if a patrol ran within the
last hour. If so, it skips the initial patrol to avoid wasting API
tokens during development/maintenance when the service is restarted
frequently.

The scheduled patrol runs (every 6 hours) are not affected.
