Implement build system for Cursor Pro with platform-specific packaging

- Added build.py script to automate the packaging process for macOS and Windows.
- Created CursorKeepAlive.mac.spec and CursorKeepAlive.win.spec for application specifications.
- Updated .gitignore to exclude build artifacts and IDE files.
- Enhanced directory structure for output files and included configuration file handling in the build process.
