Sessions: Changes in non-git repo show as pending changes in `Files` tab

[bamurtaugh]

• Use Sessions to make some changes on a repo that isn't git-initialized
• ✅ Changes are made
• ❓ If I open the Files tab, the file that was edited shows that it has pending changes that I need to keep or undo.
  • This is unexpected since I believe the Copilot CLI would've just applied the changes to my local workspace (as it couldn't use a worktree)
  • If I open Insiders, I don't see any pending changes waited to be applied (which is what I'd expect: the CLI just edited my local file directly)

If I use the CLI in a non-git repo to simply create a new file, it doesn't show any pending changes:

And further edits to this file also aren't shown as pending. I'll close for now and reopen if I get a more reliable repro.

Ah okay I see how to repro:

• From the above state (where no files were shown as pending changes), decide to go click into other agent sessions
• Then return to my previous session
• Open the Files tab
• ❓ My files are now newly marked as having pending changes I need to keep or undo

@bamurtaugh, I am unable to reproduce this with the latest builds. I would go ahead and optimistically close this issue quite some work was done for the no-git repo scenario. Please feel free to reopen it in case you are still able to reproduce. Thanks!
