Pull request overview
This PR adds support for chat session content providers to return an optional title that will be used as the display name for the session (e.g., in editor tabs). When no title is provided, the system continues to default to the first user message in the session history.
Changes:
- Added optional
titleproperty to theChatSessioninterface in the proposed API - Propagated title through the extension host protocol and main thread implementation
- Applied title to chat model using existing
setCustomTitlemethod - Added comprehensive test coverage for title propagation
