Cron vs Heartbeat — Decision Chart + JSON Snippet
=================================================

Use CRON when:
- The time must be exact (“9:00 AM sharp”).
- The task can run alone (no context).

Use HEARTBEAT when:
- You want a gentle check-in (~30–60 min).
- You want to batch checks (email + calendar + mentions).

Sample heartbeat state JSON:
{"lastChecks":{"email":1703275200,"calendar":1703260800,"weather":null}}
