Yufeng He 330d3d7165 fix(openai): drop completed continuation_token from shared options in tool loop (#5462 )

Fixes #5394.

When `background=True` is combined with local function tools,
`FunctionInvocationLayer` calls `_inner_get_response(options=mutable_options)`
repeatedly with the same dict reference across loop iterations. Once the
first poll retrieves a completed background response, `continuation_token`
stays in `mutable_options`, so every subsequent iteration takes the
`continuation_token is not None` branch and `GET`s the same completed
response instead of `POST`ing the tool results. The loop exits after
`max_iterations` with empty text and the model never sees any tool output.

After the retrieve, if the returned `ChatResponse.continuation_token` is
`None` (the background response is no longer in progress), pop
`continuation_token` and `background` from the shared options dict in
place. The next loop iteration then falls through to the normal
`responses.create`/`parse` path and posts tool results.

The diagnosis and a verified runtime monkeypatch are in the issue; this
is the same fix moved in-tree.
