Scheduler and worker loops survive a database restart
index-scheduler's loop ended when Postgres restarted (the active-groups
query was outside its try), leaving live indexing stopped for ~3 hours
while the process stayed up. Each step's error is now caught and retried
next round; worker:spots and worker:deferred wait 30 s and claim again.
