Enhance build configuration and scripts for multi-platform support

- Updated electrobun.config.ts to include environment-based settings for macOS builds. - Added new build scripts for Windows and macOS, including support for architecture-specific builds. - Introduced scripts for cleaning build artifacts, managing dependencies, and ensuring core binaries are present. - Enhanced Jenkinsfile to integrate new build processes and improve artifact management. - Added new assets for application icons and installer configurations. - Implemented NSIS and MSI packaging scripts for Windows installer creation. - Updated package.json with new scripts for development and build processes, including post-installation tasks.
