Moved from precompiled binaries to setup scripts

This should ensure better compatibility with all kinds of systems

Quick Start

Double-click on run-windows.bat
If asked for administrator permissions, please allow them (needed for Node.js installation)
If Node.js is installed during the process, you'll need to close the window and run the script again
This is because Windows needs to update environment variables after Node.js installation

Open Terminal
Navigate to the extracted directory: cd path/to/extracted/folder
Make the script executable (first time only): chmod +x run-linux.sh
Run the script: ./run-linux.sh
Note: You may need to provide your password for sudo commands if Node.js needs to be installed

If you encounter issues:

"electron is not recognized" or "Cannot find module" errors:
- Windows: Make sure to run the script again after Node.js installation completes
- Try running npm install electron --save-dev manually in the application directory
- Run the script again after installation completes
Permission issues:
- Windows: Try running the batch file as administrator
- macOS/Linux: Make sure you've made the script executable with chmod +x run-mac.sh or chmod +x run-linux.sh
Node.js installation fails:
- Windows: Download and install Node.js manually from nodejs.org
- macOS: Install Homebrew from brew.sh, then run brew install node
- Linux: Use your distribution's package manager to install nodejs and npm
WhatsApp Web connection issues:
- Make sure your computer and phone are connected to the internet
- Try restarting the application
- Ensure your WhatsApp mobile app is up to date
Windows-specific issues:
- If you see "not recognized as an internal or external command", close the command prompt window and run the script again
- Windows may need to restart the command prompt to recognize newly installed programs
- If the issue persists, try running the following commands manually in the application directory:
```
npm install
npm install electron --save-dev
npx electron .
```
