  "summary": "This PR introduces a BlockRequestTracker class to track manual on-demand block downloads initiated via the getblockfrompeer RPC. If an assigned peer disconnects or fails to respond, the node automatically retries fetching the block from another available peer. It also updates getblockfrompeer to make the peer_id parameter optional and adds a retry flag.",
