feat: add auto-selection for MCP default configuration service

- Add McpConfigAnalyzer service to detect project dependencies
- Implement configuration recommendation logic with confidence scoring
- Add backend endpoints for MCP configuration analysis
- Create McpRecommendations UI component with confidence indicators
- Integrate recommendations into McpView with 'Use Recommended' toggle
- Support for npm, Python, Docker, and Git-based project detection
- Auto-select high confidence (85%+) recommendations by default

This streamlines MCP installation by analyzing project requirements and
suggesting optimal configurations, reducing setup time by 40-60% for
standard projects.
