Add comprehensive WebSocket, context, performance, and security modules

- Introduced WebSocket client for real-time Home Assistant event streaming
- Created context management system for tracking resource relationships and state
- Implemented performance monitoring and optimization utilities
- Added security middleware with token validation, rate limiting, and input sanitization
- Extended tool registry with enhanced tool registration and execution capabilities
- Expanded test coverage for new modules and added comprehensive test scenarios
- Improved type safety and added robust error handling across new modules

 ## Troubleshooting
 
 ### Common Issues
+
 1. **Node.js Version (`toSorted is not a function`)**
    - **Solution:** Update to Node.js 20.10.0+
+   ```bash
+   nvm install 20.10.0
+   nvm use 20.10.0
+   ```
+
 2. **Connection Issues**
    - Verify Home Assistant is running
    - Check `HASS_HOST` accessibility
    - Validate token permissions
-3. **Entity Control Issues**
+   - Ensure WebSocket connection for real-time updates
-   - Verify `entity_id` exists
+
-   - Check entity domain matches command
+3. **Add-on Management Issues**
-   - Ensure parameter values are valid
+   - Verify Supervisor access
+   - Check add-on compatibility
+   - Validate system resources
+
+4. **HACS Integration Issues**
+   - Verify HACS installation
+   - Check HACS integration status
+   - Validate repository access
+
+5. **Automation Issues**
+   - Verify entity availability
+   - Check trigger conditions
+   - Validate service calls
+   - Monitor execution logs
