yusufipk d05bab4f98 Wave the agent's progress away, and say how hard it should think
Two things a real command turned up.

A job can run for ten minutes. "Report on the front page" is not a question
with an answer a second later, and having the corner narrate every tool it
touches for those ten minutes is worse than saying nothing. So that indicator
can be clicked away. It is the only one that can: a dictation is over in
seconds, and an indicator that swallows a click meant for the window underneath
has to earn it. The work carries on; what is muted is the progress, not the
outcome, which shows up whether or not the box was sent away. A faint cross on
the right says the box can be clicked, because a feature nobody can see is not
one. The next run starts visible again.

Muting leaves the state alone rather than setting it to something hidden, so no
later repaint puts the box back on the screen behind its own back.

Thinking effort is a setting now, offered once rather than three times: how hard
to think is one thing to want, and only the rungs differ. Claude takes it as
--effort, Codex as a model_reasoning_effort override, OpenRouter in the
reasoning field it already understood for cleanup. A level a provider does not
have lands on the nearest one it does, so "maximum" is xhigh on Claude and high
on Codex rather than an error or a silent drop. Left alone, nothing is sent and
each model does what it would have done.

"""OpenAI and OpenRouter calls, stdlib only.

both and only the key, the base URL and the model id change. Cleanup is always
