4666bb6503 Add mutex protection to ConsistentHashRing for thread safety
All checks were successful
CI / build (pull_request) Successful in 16s
Details 
- Add sync.RWMutex to ConsistentHashRing struct
- Use Lock/Unlock for write operations (AddNode, RemoveNode)
- Use RLock/RUnlock for read operations (GetNode, GetNodes, IsEmpty)

This allows concurrent reads (the common case) while serializing writes,
preventing race conditions when multiple goroutines access the hash ring.

Closes #35
