Describe the changes in the pull request
The HNSW neighbor debug API currently dispatches by casting indexes to the in-memory HNSW classes, so alternate HNSW backends cannot implement it safely. This adds a virtual debug hook with a fail-closed default and routes the public C API through it; the existing in-memory and tiered implementations preserve their behavior. The change is internal-only for current callers and enables disk HNSW graph inspection in RediSearchEnterprise.
