Cross-platform dependency handling for Windows and Linux

Changes

• Added platform-specific dependency logic to setup.py to conditionally include Linux-only packages
• Created requirements-linux.txt for Linux users that includes Linux-specific dependencies
• Removed direct dependencies on Linux-only packages from requirements.txt
• Maintained backward compatibility for Linux installations

Problem solved

This PR fixes installation issues on Windows systems by removing Linux-specific dependencies (evdev and python-xlib) that were causing errors during installation. At the same time, it maintains Linux compatibility by conditionally including these dependencies only when installing on Linux systems.

How to install

• Windows users: pip install -e . or pip install -r requirements.txt
• Linux users: pip install -e . or pip install -r requirements-linux.txt

Testing

• Verified installation works correctly on Windows
• Keyboard automation functionality works properly using cross-platform pynput library
