[FEATURE]: TUI: Add full-file diff toggle in permission fullscreen view #9026
Description
Feature hasn't been suggested before.
- I have verified this feature I'm about to request hasn't been suggested before.
Describe the enhancement you want to request
Problem
Permission preview only shows a 4-line context diff by default. Reviewing code changes in isolation can make it hard to understand the surrounding logic, especially for larger files.
Desired Behavior
Add a keyboard shortcut ctrl+o in fullscreen permission view to toggle between:
- Default diff (4-line context)
- Full-file diff (all lines as context)
The toggle should only appear when in fullscreen mode (afterctrl+f). - Press Ctrl+O again to return to the default 4-line context diff.
User Value
- Better context when reviewing changes
- Faster approval decisions with full-file understanding
- No breaking changes—default behavior unchanged
Design Review Required
This is a UI/core product feature and requires design review per CONTRIBUTING guidelines before implementation.
Implementation Status
✅ Implementation is complete and ready for PR after design approval.

Agree with this - also the current keybinding to fullscreen is ctrl + f - clashes with text search in VSCode, but is standard so I don't want to change the VSCode version
