feat: Update Unreal Engine MCP Server with intelligent asset path handling and other fixes (github#246)

* feat: Update Unreal Engine MCP Server with intelligent asset path handling and production-ready stability

- Added intelligent asset path handling: supports actor classes (StaticMeshActor), asset paths (/Engine/BasicShapes/Cube), and simple names (Cube, Sphere) with auto-resolution
- Enhanced AI assistant compatibility with automatic StaticMeshActor spawning for asset paths
- Fixed circular reference issues preventing JSON serialization errors in complex Unreal objects
- Improved stability with proper WebSocket error handling and response validation
- Updated descriptions to highlight production-ready features and AI-friendly usage patterns
- Successfully tested with local build (13 tools found), catalog generation, and Docker import

* Update Unreal Engine MCP Server configuration

- Remove 'Production-ready' from description
- Update default host to host.docker.internal for Docker compatibility
- Add comprehensive descriptions for all configuration parameters
- Add required fields validation
- Improve networking documentation for various deployment scenarios

* chore(server): update Unreal Engine MCP Server icon URL

* fix(unreal-engine-mcp-server): update server icon URL in metadata

+  description: MCP server for controlling Unreal Engine via Remote Control API. Features intelligent asset path handling, circular reference-safe responses, and 13 consolidated tools covering actors, assets, editor control, cinematics, physics, and more. Supports both simple shape names ("Cube") and full asset paths ("/Engine/BasicShapes/Cube") with automatic StaticMeshActor spawning. Handles common AI assistant usage patterns seamlessly.
