feat: update documentation and component demos for backend layered architecture
- Add new LanguageScopeDemo component for backend languages overview - Refactor and simplify existing demo components (ControllerLayerDemo, DtoFlowDemo, DependencyDirectionDemo) - Update .gitignore to exclude .claude/skills directory - Modify backend-related sections in documentation from "后端与全栈" to "后端开发" - Add new backend layered architecture demo components (CleanArchitectureDemo, DependencyDirectionDemo) - Improve documentation structure and content for stage-3 core skills - Fix component initialization timing in CompileVsInterpretDemo and RateLimiterDemo - Add design style prompt reference in frontend documentation
