Migrate development environment from Windows to macOS and continue project updates
- Shifted primary development environment from Windows to macOS to ensure better performance, stability, and streamlined workflow for Java development. - Removed OS-specific metadata and ensured platform-agnostic project compatibility. - Normalized line endings to LF for cross-platform consistency. - Verified and adjusted file paths, permissions, and encoding settings to suit macOS environment. - Cleaned up unnecessary Windows-generated files and updated Git configuration accordingly. - Future commits and development will now be managed entirely from macOS. This migration ensures a cleaner, more consistent setup moving forward and prepares the project for scalable development across Unix-based systems. Future development will continue on macOS for a smoother, Unix-based experience. Signed-off-by: Someshdiwan <[email protected]>
