fix: Remove 'shortcut' appearance in Xcode Project Navigator

PROBLEM:
- PBXFileSystemSynchronizedRootGroup with path = '.' created a 'shortcut' appearance
- Displayed as '.' instead of proper folder name in Xcode
- Confusing for developers

SOLUTION:
- Changed group name from '.' to 'AudioKeeper'
- Updated all references to use proper name
- Now displays as normal folder in Project Navigator

This makes the project structure clearer and more intuitive
in Xcode's Project Navigator while maintaining the same
file synchronization functionality.
