opencode run exits with status 0 for invalid model when prompt is provided

Description

Description

Running opencode run with an invalid model and a prompt/message argument produces a ProviderModelNotFoundError, but the process exits with status code 0.

This only appears to happen when a prompt/message is provided.

Command

opencode run -m invalid-model "some message"
echo $?

Plugins

This issue might be a duplicate of existing issues. Please check:

• BUG: exit code when an invalid model is passed #15558: BUG: exit code when an invalid model is passed (closed) — same bug: opencode run --model invalid-model-123 "test" exits with code 0
• Error returns exit code 0 #17854: Error returns exit code 0 (closed) — same issue with invalid model returning exit code 0

Both are closed; if the fix was reverted or the behavior regressed, it may be worth referencing those issues and confirming the version where it was fixed.

Have a small fix for this — setting process.exitCode = 1 in the session.error handler inside run.ts's loop(), which matches the existing pattern in thread.ts and attach.ts. Opening a PR shortly.

For context, prior attempt PR #15787 (same bug as surfaced in #15558 / #17854 / #2489) was auto-closed by the template-compliance bot before any human review.

Happy to defer if anyone's already working on it.
