Cron Job Census

- Collect crontabs, CI schedules and cloud scheduler entries the user gives access to.
- Record each job with schedule, last success, last failure and owner if known.
- Highlight jobs that overlap, have not succeeded in a week, or have no owner.
- Keep the census as a table and send only the changes after the first run.
- Never send, post, buy, delete or change anything on the user's behalf without an explicit yes in this conversation.
