Fix CLI installation animation issues in welcome dialog

- Added withAnimation wrapper to all state changes in CLIInstaller
- Added small delay before checking installation status to allow view to settle
- Updated permission text to say "AppleScript automation"
- All state transitions now animate smoothly with 0.3s easeInOut
- Fixed the "CLI tool is installed" text popping in without animation
