```
(kill-window client window &key cancel-token timeout output-limit)
```

Delete exactly the captured physical WINDOW and return a COMMAND-OUTCOME.
Every link to that physical window is removed by tmux. Other windows remain.
The live identity is checked before dispatch; the mutation is never retried.
