`/cd` command results is not understood by rewind

[davidwengier]

Describe the bug

I opened copilot in a normal folder, not a git repository, then ran /cd razor to get into a git repository. Later, when trying to rewind, it said it couldn't because I wasn't in a git repository.

See screenshot below. Started in C:\Code, cd'd into razor, and am clearly in a git repository because the branch info is shown

Affected version

GitHub Copilot CLI 0.0.400.

Steps to reproduce the behavior

1. Navigate to a folder that is a parent of a git repository
2. Run copilot
3. /cd into the git repository
4. Press Esc twice

Expected behavior

It should know that I'm in a git repository because I used the /cd command to get there.
