test: Add comprehensive unit tests for ComponentResolver and intelligent property matching
- Add AIPropertyMatchingTests.cs with 14 tests covering property enumeration, fuzzy matching, caching, and Unity naming conventions - Add ManageGameObjectTests.cs with 10 integration tests for component resolution, property matching, and error handling - Add ComponentResolverTests.cs.meta for existing comprehensive ComponentResolver tests - Add AssemblyInfo.cs.meta for test assembly access - Fix ManageGameObject.HandleCommand null parameter handling to prevent NullReferenceException All 45 unit tests now pass, providing full coverage of: - Robust component resolution avoiding Assembly.LoadFrom - Intelligent property name suggestions using rule-based fuzzy matching - Assembly definition (asmdef) support via CompilationPipeline - Comprehensive error handling with helpful suggestions 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
