rka-oai 763787d061 Support standalone named function call outputs (#39782) ...

## Why

External tool events may need to enter thread history without a preceding function call and therefore do not have a `call_id`.

## What changed

- Allow `function_call_output` items to omit `call_id` and carry optional `name` and `namespace` fields.
- Preserve named standalone outputs during history normalization and agent forks while retaining existing pairing behavior for outputs with a `call_id`.
- Accept, persist, and forward these outputs through `thread/inject_items`, and update the app-server schemas and documentation.

## Testing

- Cover paired and standalone JSON round trips, history normalization, agent forks, and injected thread history.
