acb-index-builder has been in CrashLoopBackOff for 45 days with silent crashes
after "Copied web assets to output directory". Investigation revealed O(n²) N+1
query loops causing unbounded memory growth and OOMKill.
Changes:
- fetchSeries: batch games query (1000 queries → 1 query) with LIMIT 10000
- fetchChampionshipBracket: batch games query (500 queries → 1 query) with LIMIT 64
- fetchSeasonSnapshots: reduce LIMIT from 10000 to 500
- fetchLineage: reduce LIMIT from 10000 to 1000
- Add strings import for strings.Join in batch queries
These changes prevent the pod from being OOMKilled during fetchAllData() which
runs after copyWebAssets() in the build cycle.
