pub fn cleanup_stale_shared(shared_dir: &Path, max_age_ms: u64)Expand description
Startup sweep over the host-global registry: remove any entry whose
updated_at is past max_age_ms OR whose pid is no longer alive on
this host (§4.4) — the dead-Agent3 case from the spec’s problem
statement, where per-channel TTL cleanup never reached an entry
belonging to a channel that hadn’t restarted.
