Hotfix release for the Timeline window chrome and hidden toolbar restore control.
Fixed:
- Restores the native macOS close, minimize, and zoom buttons in the release build.
- Allows the Timeline window to resize while preserving its aspect ratio and minimum usable size.
Improved:
- Makes the hidden-toolbar restore control a compact 44pt icon button so it blocks less Live Text selection area.
- Keeps a subtle top chrome band behind the native window controls while the scrubber/app toolbar remains independently hideable.
