feat: add comprehensive Windows/WSL support and documentation

Major improvements for Windows users:
- Add detailed Windows Setup Guide with native and WSL options
- Create platform-specific example configurations (Windows/WSL/macOS)
- Add troubleshooting section addressing common Windows/WSL errors
- Create test_wsl_setup.bat diagnostic script for Windows users

Script improvements:
- Enhance run_gemini.bat with error handling and helpful messages
- Update both run scripts to use server.py as main entry point
- Keep gemini_server.py as backward compatibility wrapper

Documentation:
- Add clear instructions for both native Windows and WSL setups
- Explain the wsl.exe bridge approach for WSL users
- Include performance recommendations for WSL file access
- Add specific troubleshooting for spawn ENOENT errors

All tests passing, code properly formatted and linted.

+## Windows Setup Guide
+
+### Option 1: Native Windows (Recommended)
+
+For the smoothest experience on Windows, we recommend running the server natively:
+
+1. **Install Python on Windows**
+   - Download from [python.org](https://python.org) or install via Microsoft Store
+   - Ensure Python 3.10 or higher
+
+2. **Set up the project**
+   ```powershell
+   cd C:\Users\YOUR_USERNAME\gemini-mcp-server
+   python -m venv venv
+   .\venv\Scripts\activate
+   pip install -r requirements.txt
+   ```
+
+3. **Configure Claude Desktop** using the Windows native configuration shown above
+
+### Option 2: Using WSL (Advanced)
+
+If you prefer to use WSL (Windows Subsystem for Linux):
+
+1. **Prerequisites**
+   - WSL2 installed with a Linux distribution (e.g., Ubuntu)
+   - Python installed in your WSL environment
+   - Project cloned inside WSL (recommended: `~/gemini-mcp-server`)
+
+2. **Set up in WSL**
+   ```bash
+   # Inside WSL terminal
+   cd ~/gemini-mcp-server
+   python3 -m venv venv
+   source venv/bin/activate
+   pip install -r requirements.txt
+   chmod +x run_gemini.sh
+   ```
+
+3. **Configure Claude Desktop** using the WSL configuration shown above
+
+**Important WSL Notes:**
+- For best performance, clone the repository inside WSL (`~/`) rather than on Windows (`/mnt/c/`)
+- Ensure `run_gemini.sh` has Unix line endings (LF, not CRLF)
+- If you have multiple WSL distributions, specify which one: `wsl.exe -d Ubuntu-22.04`
+

+## Troubleshooting
+
+### Windows/WSL Issues
+
+**Error: `spawn P:\path\to\run_gemini.bat ENOENT`**
+
+This error occurs when Claude Desktop (running on Windows) can't properly execute the server. Common causes:
+
+1. **Wrong execution environment**: You're trying to run WSL-based code from Windows
+   - **Solution**: Use the WSL bridge configuration with `wsl.exe` (see Windows Setup Guide above)
+
+2. **Path format mismatch**: Using Linux paths (`/mnt/c/...`) in Windows context
+   - **Solution**: Use Windows paths for native execution, Linux paths only after `wsl.exe`
+
+3. **Missing dependencies**: Python or required packages not installed in the execution environment
+   - **Solution**: Ensure Python and dependencies are installed where you're trying to run (Windows or WSL)
+
+**Testing your setup:**
+- Windows users: Run `test_wsl_setup.bat` to verify your WSL configuration
+- Check Python availability: `python --version` (Windows) or `wsl python3 --version` (WSL)
+
+### Common Issues
+
+**"GEMINI_API_KEY environment variable is required"**
+- Ensure you've added your API key to the Claude Desktop configuration
+- The key should be in the `env` section of your MCP server config
+
+**"Connection failed" in Claude Desktop**
+- Verify the command path is correct and uses proper escaping (`\\` for Windows paths)
+- Ensure the script has execute permissions (Linux/macOS: `chmod +x run_gemini.sh`)
+- Check Claude Desktop logs for detailed error messages
+
+**Performance issues with WSL**
+- Files on Windows drives (`/mnt/c/`) are slower to access from WSL
+- For best performance, clone the repository inside WSL (`~/gemini-mcp-server`)
