What does this PR do?
Adds
hermes cron daemoncommand to run the cron scheduler as a standalone process, independent of the gateway.Problem: Cron jobs don't execute on systems where the gateway isn't running (Windows without service installation, headless servers, etc.). The cron scheduler only runs inside the gateway process, so if the gateway isn't started, cron jobs never fire.
Solution: New
hermes cron daemoncommand that runs the same tick loop as the gateway's internal cron ticker, but as a standalone process.Changes Made
hermes_cli/cron.py: Addedcron_daemon()function that runs the cron tick loop with signal handlinghermes_cli/main.py: Addeddaemonsubcommand parser with--intervaloption (default 60s)How to Test
Create a cron job:
Start the cron daemon:
Verify the job executes (check
hermes cron listforlast_run_at)Stop with Ctrl+C

Fixes #41037 (Cron jobs never execute: last_run_at always null after manual trigger)
