* fix(tui): let quit skip an interrupted run's unfinished step
After Ctrl+C the synchronous agent stream keeps running until its next
event. The run was a Textual thread worker, i.e. a thread on asyncio's
default executor, which App.run() joins on shutdown (up to 300 s on
3.12) and interpreter exit joins again with no timeout. Quitting while
a long step was still running therefore hung silently after the
terminal had been restored, and further Ctrl+C presses only printed a
traceback.
Run workers on a daemon thread instead. Quit now waits visibly for
running workers (an interrupted step still checkpoints, a finished run
still saves its title) and refuses sends meanwhile; a second quit
request exits at once. Report unexpected worker exceptions as an error
row and end the run, since Textual no longer catches them.

* fix(tui): keep a refused message in the composer
on_composer_input_submitted cleared the composer before _send_to_agent
decided whether it could start a run. A prompt typed during an active run,
while an interrupted run on the same thread was still stopping, or when the
worker failed to start was replaced by a notice and survived only in input
history.
_send_to_agent now reports whether it started a run, and the submit handler
puts the exact submitted text back with the cursor at its end, so Enter
resends it. Accepted messages and local slash commands clear the composer as
before.
* fix(tui): keep a launch message that fails to start in the composer
on_mount sent the launch message through _send_to_agent and ignored the
result, so a worker start failure lost the message: it never reached the
composer or input history. Route both the launch message and composer
submissions through one _restore_draft helper.

* fix(tui): keep the palette closed over a restored slash draft
Restoring a refused bare skill activation such as /tdd posted
TextArea.Changed, which reopened the command palette, so Enter filled the
skill instead of resending it. Remember the restored draft and keep the
palette closed until it is edited. Restore the history copy of the text too,
so a trimmed slash command matches what Up recalls.
* fix(tui): wait for an interrupted run before sending to its thread
Textual cannot stop a thread worker, so after an interrupt the agent
stream keeps running until its next event. A tool step already in
progress still completes and checkpoints while a new prompt runs on the
same thread; whichever run checkpoints last becomes the thread's state,
so the new turn could drop out of the conversation history.
Track when each worker actually starts and returns (Textual reports a
cancelled thread worker finished at once) and reject sends to a thread
whose interrupted worker is still running. Other threads stay usable,
and a worker cancelled before it started holds nothing.
