agent gets into a weird state when you interrupt during thinking

[adboio]

problem

(this is light, sorry, i'll update the issue when it happens again with more details and try to get something reproducible)

when you do this:

• agent is running, in "thinking" state
• interrupt (stop or esc)
• send a new message

then:

• the UI still shows the original thinking spinner, still spinning, in addition to the new state. like this:

[prompt A]

[some agent output]

⌛ thinking...

[prompt B]

🧠 booping...

• the agent seemingly finishes the next turn (in response to prompt B)
• agent never outputs, it just says Interrupted by user
  • as if the interruption was applied, but also queued up for later
• send another message (prompt C) and it starts streaming the response to user prompt B
• turn finishes
• agent immediately starts working on prompt C

root cause

no clue yet, but it feels like:

1. the interruption is correctly applied during the thinking state, after prompt A
2. prompt B is submitted and the agent starts on it, but somehow the interrupt signal is still queued up
3. agent finishes processing prompt B but then receives the queued interrupt signal
4. prompt C triggers the agent but it has queued output from prompt B??
5. prompt B output finishes streaming, agent immediately picks up prompt C as if it was queued?
