- Combine Extend/Mirror into a single toggle button, moved behind edit_mode
- All edit-mode controls (All Files, All Sessions, Display) now share consistent preset-tonal-tertiary styling
- Remove the always-visible display row and its non-native-mode disclaimer
- Wrap Menu_launcher_controls in mt-auto to keep it pinned to the bottom of the sidebar regardless of session count
- Add min-w-20 to file size chip to prevent collapse on narrow sessions
