Refactor user-message-hook.js and worker-utils.ts for improved logging and Windows compatibility

- Enhanced logging functionality in user-message-hook.js to include better formatting and error handling.
- Updated worker-utils.ts to escape single quotes in PowerShell commands and added checks for global PM2 installation.
- Improved readability and maintainability of the code by restructuring and clarifying variable names.
