Module scheduler 

Session-scoped cron scheduler matching Claude Code’s /loop semantics.

The scheduler holds Tasks in memory and (optionally) persists them to disk so a --resume <session_id> can restore them. Each tick advances due tasks: recurring tasks have their next_fire updated; one-shot tasks are removed after firing. Recurring tasks expire 7 days after creation; their final fire is delivered, then they are removed.

See https://code.claude.com/docs/en/scheduled-tasks for the spec.
