* fix(studio): check job_run_details size in cron display
When cron.job_run_details grows too large (200k+ rows), loading the
cron jobs overview can timeout and affect other queries by pulling
excessive data into shared buffers.
This change:
- Estimates table size using pg_stat before fetching cron jobs data
- Shows a cleanup notice when the table exceeds the threshold
- Provides batched deletion using ctid ranges to avoid buffer pollution
- Allows scheduling an automated daily cleanup cron job
- Handles timeout errors gracefully with a "suspected overflow" state
The useCronJobsData hook now returns a discriminated union status that
tracks loading, estimate-error, overflow-confirmed, overflow-suspected,
and ready states, allowing the UI to respond appropriately to each case.
* fix(studio): use index when querying cron.job_run_details
cron.job_run_details is only indexed by runid, not by start_time. Change
the query to use the runid index (which gives the same result, since
runid is auto-incrementing).
* added queues and keys to fetch version
* updated to support postREST queue management
* updated to use existing hook
* removed unused keys
* - added semvar lib
- updated logic to use semvar lib
* The conditional read was added in 1.5.0.
