Multi-node startups (Kubernetes StatefulSets, bare-metal, VMs) can hit transient DNS/local-host resolution failures while peers and headless service records are still coming up. Previously endpoint resolution retried DNS for a fixed 90s window and then returned an error, which propagated out of run() and exited the process; in Kubernetes this drove repeated kubelet restarts even though the cluster eventually converged. Introduce a startup topology convergence policy with three modes: - orchestrated: wait effectively indefinitely for recoverable DNS/topology errors so the process stays Running (readiness stays false) instead of exiting; defer the DNS-IP cross-port validation because headless-service records can still be flapping. - bounded: wait a finite window (default 3m) then fail with an action-oriented error listing host/stage/elapsed and remediation hints. - fail-fast: fail on the first non-transient resolution error. Mode is auto-detected (Kubernetes -> orchestrated, distributed URL endpoints -> bounded, local path endpoints -> fail-fast) and can be overridden via RUSTFS_STARTUP_TOPOLOGY_WAIT_MODE, RUSTFS_STARTUP_TOPOLOGY_WAIT_TIMEOUT and RUSTFS_STARTUP_TOPOLOGY_RETRY_MAX_DELAY. Also normalize divergent local/remote verdicts for endpoints that share a host:port, throttle retry warnings, and keep the DNS-independent local same-path checks in every mode. Configuration error handling is unchanged: malformed volumes, mixed styles/schemes, duplicate or root paths, and non-transient errors still fail fast. Read the topology env vars through rustfs_utils::get_env_opt_str for consistent alias handling, and simplify the log_once poisoned-lock branch to unwrap_or_else(PoisonError::into_inner).
