Backend: Fix three race conditions in SetSnapshot that caused account scheduling anomalies and broken sticky sessions: - Use Lua CAS script for atomic version activation, preventing version rollback when concurrent goroutines write snapshots simultaneously - Add UnlockBucket to release rebuild lock immediately after completion instead of waiting 30s TTL expiry - Replace immediate DEL of old snapshots with 60s EXPIRE grace period, preventing readers from hitting empty ZRANGE during version switches Frontend: Remove serial queue throttle (1-2s delay per request) from usage loading since backend now uses passive sampling. All usage requests execute immediately in parallel.
