Allow adding vscode timeline (local history) to Context

[PrestonTaylor]

I'd like to be able to ask copilot: "What was I working on yesterday" Currently in the spirit of this feature you can only add "changes" to context which appears to use git commits which isn't necessarily going to contain anything useful since most people don't make a commit every time they step away. The reply from this with "changes" referenced will contain all the work I've modified in the last week or 2 or even more rather than just what I did yesterday.
