feat: Complete NAO6 ROS2 integration for HRIStudio

🤖 Full NAO6 Robot Integration with ROS2 and WebSocket Control

## New Features
- **NAO6 Test Interface**: Real-time robot control via web browser at /nao-test
- **ROS2 Integration**: Complete naoqi_driver2 + rosbridge setup with launch files
- **WebSocket Control**: Direct robot control through HRIStudio web interface
- **Plugin System**: NAO6 robot plugins for movement, speech, and sensors
- **Database Integration**: Updated seed data with NAO6 robot and plugin definitions

## Key Components Added
- **Web Interface**: src/app/(dashboard)/nao-test/page.tsx - Complete robot control dashboard
- **Plugin Repository**: public/nao6-plugins/ - Local NAO6 plugin definitions
- **Database Updates**: Updated robots table with ROS2 protocol and enhanced capabilities
- **Comprehensive Documentation**: Complete setup, troubleshooting, and quick reference guides

## Documentation
- **Complete Integration Guide**: docs/nao6-integration-complete-guide.md (630 lines)
- **Quick Reference**: docs/nao6-quick-reference.md - Essential commands and troubleshooting
- **Updated Setup Guide**: Enhanced docs/nao6-ros2-setup.md with critical notes
- **Updated Main Docs**: docs/README.md with robot integration section

## Robot Capabilities
- ✅ **Speech Control**: Text-to-speech with emotion and language support
- ✅ **Movement Control**: Walking, turning, stopping with configurable speeds
- ✅ **Head Control**: Precise yaw/pitch positioning with sliders
- ✅ **Sensor Monitoring**: Joint states, touch sensors, sonar, cameras, IMU
- ✅ **Safety Features**: Emergency stop, movement limits, real-time monitoring
- ✅ **Real-time Data**: Live sensor data streaming through WebSocket

## Critical Discovery
**Robot Wake-Up Requirement**: NAO robots start in safe mode with loose joints and must be explicitly awakened via SSH before movement commands work. This is now documented with automated solutions.

## Technical Implementation
- **ROS2 Humble**: Complete naoqi_driver2 integration with rosbridge WebSocket server
- **Topic Mapping**: Correct namespace handling for control vs. sensor topics
- **Plugin Architecture**: Extensible NAO6 action definitions with parameter validation
- **Database Schema**: Enhanced robots table with comprehensive NAO6 capabilities
- **Import Consistency**: Fixed React import aliases to use ~ consistently

## Testing & Verification
- ✅ Tested with NAO V6.0 / NAOqi 2.8.7.4 / ROS2 Humble
- ✅ Complete end-to-end testing from web interface to robot movement
- ✅ Comprehensive troubleshooting procedures documented
- ✅ Production-ready launch scripts and deployment guides

## Production Ready
This integration is fully tested and production-ready for Human-Robot Interaction research with complete documentation, safety guidelines, and troubleshooting procedures.
