Context

PR #1384 (OpenCode provider) has a skipped abort test at \packages/providers/src/community/opencode/provider.test.ts:506.

Current State

\\ ypescript
// TODO(#1384): Enable once abort handling is stable in embedded runtime
test.skip('aborts session on signal', async () => { ... });
\\

Why Skipped

The embedded runtime's abort behavior is not yet deterministic under the current mock architecture, making the test flaky.

Acceptance Criteria

• Mock the runtime stream and abort signal deterministically
• Trigger \AbortController.abort()\ at a controlled point
• Assert:
  • Expected pre-abort chunks emitted
  • Final error is 'OpenCode query aborted'\
  • 
    untime.client.session.abort\ called with correct session payload
  • Stream cleanup occurs

Priority

Minor - test coverage improvement, not blocking production functionality.
