Why: relaxAndRemove cleared the per-exec id directory but left the -ws parent behind, so every conversation accumulated an empty husk - the live probe caught it in the workspace listing. Evidence: go test ./... green; TestOverlayCleansShellDir pins the behavior with a real bwrap roundtrip. Impact: One extra os.Remove of the (now empty) parent; failures are best-effort as before.
