Description

Improve Entity Retrieval with Memoization and Thread-Safe Caching

PR Description:

This PR adds a GetEntitiesMemoized function ( memoized version of getEntities function with a thread-safe cache (RegistryEntityCache) ) . This improves performance by avoiding redundant entity lookups and ensures safe concurrent access when multiple goroutines interact with the cache.

Key Changes:

• Implemented memoization: Avoids redundant calls to rm.GetEntities(f) by caching previously fetched results.
• *RegistryEntityCache**: A dedicated struct for entity caching, now using sync.Map for thread safety.
• thread safe cache access*: Added Get and Set methods to RegistryEntityCache for cleaner and safer interactions.

Why This Change?

• Performance Boost: Eliminates unnecessary entity lookups ( when doing bulk lookups like in case of design hydration) , reducing database/API load.
• Thread Safety: Prevents race conditions when accessing the cache concurrently.
• Cleaner Abstraction: Encapsulates caching logic inside RegistryEntityCache, making GetEntitiesMemoized easier to maintain.
