[FEATURE]: opencode run --timeout=60s

[segoon]

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

If running opencode run in scripts, I want to see it explicitly fail if it cannot finish in X seconds.

someone has a pr that will address this soon

@segoon See #3498
Note that this PR is about a timeout for a single opencode model request (calls to the underlying LLM). An execution of opencode run can produce dozens of LLM calls.

If you need to timeout the entire opencode run loop after X seconds, you should do that externally using whatever system you're using. If called from bash, there are multiple ways to timeout any script. If called from a python or JS code, use the builtin timeout features (option timeout for child_process::spawn for example).

It should not be the responsibility of opencode to ensure a maximum duration is respected for the entire loop, since it can be monitored from outside tools.
