Closes #37777 --- OpenRouter can return OpenAI Responses reasoning item IDs such as `rs_*` in assistant reasoning details. Those IDs are not reliably resolvable on a later OpenRouter turn, so replaying them can make otherwise-valid multi-turn conversations fail with a provider 404. This keeps the useful reasoning payload while removing only the ephemeral Responses item IDs before serializing `reasoning_details` back into request history. Non-Responses IDs and reasoning text are left intact.
