Subject: [PATCH] fix: ensure subtask results are provided to GPT-5 in OpenAI
 Responses API (#7305)

When a subtask completes and the parent task resumes, set skipPrevResponseIdOnce = true
to ensure the next API call sends the full conversation including the subtask result.
This fixes the issue where GPT-5 would only receive the new message without the subtask
result context when using previous_response_id.

Fixes #7251
