feat: add initialization script and improve maintenance process

- Added `init.sh` script for environment setup, including PHP, Composer, NVM, and Node.js configuration.
- Simplified Composer installation logic by removing redundant lines in `update-stufis.sh`.
- Enhanced project development environment setup with automated dependency installation.
