libtmux:detach-client

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.
