feat: Add installation scripts for Windows and Unix-based systems
- Created `install_and_run.bat` for Windows installation and setup. - Created `install_and_run.sh` for Unix-based systems installation and setup. - Removed `main.py` as it is no longer needed. - Updated `requirements.txt` to specify package versions and added PyQt5. - Deleted `start.bat` as it is redundant. - Added unit tests for core functionality and scraping modes. - Implemented input validation utilities in `utils/validators.py`. - Added support for dual scraping modes in the scraper.
