Scheduled agents

Schedules let an existing agent execute recurring work using standard five-field cron expressions and an IANA timezone.

Examples:

The Laravel scheduler checks due schedules once per minute. Dispatch uses an atomic next_run_at update to prevent the same due occurrence from being queued twice by competing scheduler processes.

Scheduled work follows the exact same capability policy as manually started runs. An unattended schedule cannot silently elevate itself to destructive or secret access.
