```
(detach-client client target &key cancel-token timeout output-limit)
```

Request detachment of captured terminal TARGET; return a COMMAND-OUTCOME.
CLIENT must own the observation. Success acknowledges the server's request,
not frontend process exit or terminal restoration. Returns no replacement.
Blocks under the supplied limits. The unique name/PID/creation/tty preflight
cannot exclude replacement between validation and dispatch. Missing or foreign
targets signal STALE-TARGET; external failures retain their outcome. Never
retries, detaches other clients, kills a parent, or starts a shell command.
