feat: enhance cloud storage path detection in sdk-options

- Introduced macOS-specific cloud storage patterns and home-anchored folder detection to improve accuracy in identifying cloud storage paths.
- Updated the isCloudStoragePath function to utilize these new patterns, ensuring better handling of cloud storage locations.
- Added comprehensive unit tests to validate detection logic for various cloud storage scenarios, including false positive prevention.
