- Reduce fetchBots LIMIT from 10000 to 2000
- Reduce fetchRatingHistory LIMIT from 10000 to 5000
- Reduce fetchFeedback LIMIT from 5000 to 1000
- Fix O(n²) participant name lookup in generateBotProfiles by using botNameMap
- Add panic recovery in runBuildCycle to log panics via slog before crashing
- Add R2/B2 client helper functions in s3.go
This fixes acb-index-builder CrashLoopBackOff caused by OOMKill after
web asset copy. The pod was silently crashing during fetchAllData()
due to unbounded query results consuming all memory.
