"terminated command after exceeding timeout" message does not work on all programs

[divinity76]

Description

When a command timeouts and gets terminated, we're supposed to get a indicator in the form of

<shell_metadata>
shell tool terminated command after exceeding timeout 120000 ms. If this command is expected to take longer and is not waiting for interactive input, retry with a larger timeout value in milliseconds.
</shell_metadata>

But that message does not always appear, presumably depending on the terminal output of the program that was terminated.

Interestingly, it seems to always appear in the /share log, but not in the terminal.

1.15.0

Steps to reproduce

printf '#!/bin/sh\nopencode' | sudo tee /usr/local/bin/ccc; sudo chmod a+x /usr/local/bin/ccc; opencode --prompt 'what is the local ccc command?'

Note: It only reproduce if the llm actually try to invoke the ccc command. With that query, there's a high likelyhood of GPT* models trying to invoke it with ccc --help
