pmccrary-oai 2e4675919e Inject history notes hints into context windows (#40539) ...

## What changed

- Register the history-notes extension as a context contributor and fetch `thread_hint` from the configured history-notes backend.
- Add non-empty hints of at most 4,000 bytes to the context-window prompt, and omit hints when the request fails or the response is missing, empty, or oversized.
- Verify that app-server sessions use the native backend when `use_history_notes_extension` is enabled and retain the MCP bridge behavior when it is disabled.

## Testing

- Cover hint injection, request context, response validation, backend failures, and disabled-extension behavior in history-notes and app-server tests.
