feat: add setup scripts and improve dependency installation

- Add setup.sh for macOS/Linux with dependency installation
- Add setup.bat for Windows with dependency installation
- Update README with clearer setup instructions in Quickstart
- Add troubleshooting for "ModuleNotFoundError: No module named 'mcp'"
- Provide manual installation steps as fallback

This helps users avoid the common "ModuleNotFoundError" by ensuring
dependencies are properly installed before first use.

+- Install all required dependencies (mcp, google-genai, etc.)
+- Verify your Python installation

+**"ModuleNotFoundError: No module named 'mcp'"**
+- This means Python dependencies aren't installed
+- **Solution**: Run the setup script:
+  - macOS/Linux: `./setup.sh` 
+  - Windows: `setup.bat`
+- If you still see this error, manually activate the virtual environment and install:
+  ```bash
+  # macOS/Linux:
+  source venv/bin/activate
+  pip install -r requirements.txt
+  
+  # Windows:
+  venv\Scripts\activate.bat
+  pip install -r requirements.txt
+  ```
+
+**"Virtual environment not found" warning**
+- This is just a warning that can be ignored if dependencies are installed system-wide
+- To fix: Run the setup script to create the virtual environment
+
 **"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
