Enrich Hook data (add sessionId and assistantResponse to hook events) #2458
Description
Describe the feature or problem you'd like to solve
When a github hook is triggered, it should include the session ID as part of the hook data.
Proposed solution
Currently, when interacting with the Copilot Hooks, there is no way to tell when a sessionEnd hook gets triggered for a particular session. The sessionEnd hook also doesn't include the assistant's final response or summary message for the session.
If possible, these hooks could be greatly improved (especially sessionEnd), by adding a reference to the copilot sessionId (the sessionStart could benefit from this too), this could let us track sessions in external systems and properly alert/close off and report on the status of a specific conversation using these hooks. Currently, this is not possible.
It would also be useful to be able to get the assistant's response within the sessionEnd hook as well.
