Add scheduled jobs (crons)
Define recurring jobs in convex/crons.ts targeting internal functions, with sane intervals and idempotent handlers.
Steps
- Create convex/crons.ts with cronJobs().
- Schedule internal functions (never public api.*) at the right interval.
- Make handlers idempotent (safe to re-run); keep each run small.
- Verify the job appears in the dashboard schedule.
Rules
- Schedule internal.* functions, never api.*.
- Keep cron handlers small + idempotent.
- Don't poll tight intervals for things a subscription can push.
