```
(unset-option client name &key scope target (key nil key-p) cancel-token timeout output-limit)
```

Remove one local option or array entry and return its COMMAND-OUTCOME.
SCOPE/TARGET and KEY follow SET-OPTION. The exact live catalog validates the
name, table and array shape before payload dispatch. Tmux's native unset/default
behavior applies; inherited state is not silently materialized. See SET-OPTION
for setting and scope rules. Never retries.
