chore: add changeset for early feedback feature

When the model generates large diffs (especially for notebooks), there
was a long perceived delay between the model's thinking and the edit
dialog appearing. The file path is available within milliseconds, but
the UI waited for diff content to start streaming.

Now shows "Preparing to edit {filename}..." immediately when a complete
file path is detected, giving users instant feedback that an edit is
in progress.

+feat: Show early feedback when editing files

+Display immediate visual feedback in the diff view when file edits begin, improving user experience by showing progress earlier instead of waiting for the first content chunk to arrive.
