[General] Need basic file editing directly in the tool.

**Mood:** 😊
**Category:** General

Need basic file editing directly in the tool. View changes is cute, but having to open VS Code to edit / tweak a file, or populate an env file, feels silly when basic file edit functioanlity (at least on par with notepad) is expected.

Start at the /chat experience described in the issue and review how the app currently presents file changes. Define the supported basic editing scope and confirm that users can edit or populate files directly without opening VS Code; the issue provides no file or test entry points.
