Problem

The LazyLoader class had a minor memory leak where pending promise references were not cleaned up
during cache eviction or clearing.

Changes

• evictLRU(): Added cleanup of pendingLoads when evicting entries
• clear(): Now clears pendingLoads to prevent promise accumulation
• Reduced default cache size: From 100k to 50k entries to reduce memory footprint

Impact

• Prevents accumulation of orphaned promise references

Testing

• added tests & old tests still pass
