- Migrate all log.Printf/log.Println calls to structured zap logging - Use cmp.Or for cleaner default value handling - Replace manual loops with slices.ContainsFunc/IndexFunc - Add batch query methods (IsLikedBatch, IsFavoritedBatch) to solve N+1 problem - Update JSON tags from omitempty to omitzero for numeric fields - Use errgroup-style wg.Go for worker goroutines - Remove duplicate casbin/v2 dependency (keeping v3) - Add plans/ to gitignore
