feat: Implement application bootstrap and window management

- Added bootstrap functionality to initialize the Electron application.
- Created a new paths module to manage application paths and URLs.
- Introduced a shutdown service to handle graceful application shutdowns.
- Refactored error logging to use a dedicated logger module.
- Implemented process killing logic for NodeCG processes across platforms.
- Established navigation policies for internal and external URL handling in windows.
- Developed window service for creating and managing application windows.
- Added tests for application paths, application controller, navigation policies, process killer, and shutdown service.
