Minor Enhancements to Replica Cloning and Fetching Mechanism in Replication Queue

Why it matters

This feature addresses extremely rare cases where GET_PART entries in the replication queue could hang, potentially causing delays or inconsistencies in replicated data. By improving replica cloning and the logic for enqueuing fetch operations for broken parts, the replication process becomes more robust and reliable.

How to use it

No explicit configuration is required. The improvements are integrated into the replication mechanism internally, automatically enhancing replica cloning and fetch enqueuing behavior to prevent GET_PART queue hangs.
