Function parse_leader_hint

nodedb-cluster/src/bootstrap/join.rs:57–61

Parse a `JoinResponse::error` string as a leader redirect hint. The prefix is defined as a shared constant in `rpc_codec` (`LEADER_REDIRECT_PREFIX`) so the producer side (`raft_loop::join::join_flow`) and this consumer can never drift. Any other kind of rejection (collision, parse error, catalog persist failure, commit timeout, etc.) is treated as a hard failure that bubbles through the normal er
