Generic mutex-protected set (a map[K]struct{} wrapper) with set-algebra operations.

Key API

• ThreadSafeSet[K comparable] struct; NewThreadSafeSet[K]() *ThreadSafeSet[K].
• Methods: Clear, Copy/CopyRaw, Delete/DeleteMultiple, Has, Iterate/IterateOnCopy/IterateWithBreak, Length, IsEmpty, MarshalJSON, Pop, Set, ImportFromMap(map[K]struct{}), String, Values, IsEqual(other), Union(other), Difference(other), SymmetricDifference(other), Intersect(other).

Usage Notes

• Thread-safe via sync.RWMutex. Iterate/IterateWithBreak hold the read lock during the callback — mutating the same set inside the callback deadlocks; use IterateOnCopy instead.
• Union/Difference/Intersect/SymmetricDifference return new sets built from snapshots, so callers can mutate either source set after the call without changing the result.
• No dependency on other repo packages; used internally by yatgstorage to track lazily-initialized RedisJSON state keys.
