feat: enhance installation script to support user switching and directory setup

- Updated the installation directory to a specific path (`/home/debros`) for better organization.
- Added a function to check and switch to the 'debros' user if not already running as that user.
- Improved user creation logic to ensure the 'debros' user is set up correctly with the appropriate home directory.
- Enhanced directory setup to create necessary subdirectories and set permissions accordingly.
