[FEATURE] Update Diff/File Panel immediately

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When Claude creates (or deletes) a commit, files or directories I'd expect that I see it immediately in the files/diff dialog (at least after the prompt has finished)

But actually I not only do not see the current state of the directory/git branch, but I even have no option to reload them.

Proposed Solution

Either watch files and update them directly on change (like vscode) or update files, directories and git commits always when a prompt finished.

Alternative Solutions

Provide a "Refresh" button (including keyboard shortcut)

Priority

Critical - Blocking my work

Feature Category

Developer tools/SDK

Use Case Example

1. open file pane (Ctrl-Shift-F)
2. ask claude to create a file
3. look at file pane: no file visible
