Add comprehensive component library and demo application

Added extensive component library with feedback components (empty state, loading spinner, skeleton loader), enhanced form components (autocomplete, date picker, file upload, form field, time picker), navigation components (pagination), and overlay components (backdrop, drawer, modal, overlay container). Updated demo application with comprehensive showcase components and enhanced styling throughout the project. Excluded font files from repository to reduce size.

-## Development Notes
+## Development Workflow
 
-- All libraries use Angular 19.2+ with strict TypeScript configuration
+### Component Development
+1. **New components**: Add to appropriate category in `ui-essentials/src/lib/components/`
+2. **Export new components**: Update category `index.ts` files  
+3. **Demo components**: Create matching demo in `demo-ui-essentials/src/app/demos/`
+4. **Routing**: Add demo routes to `demos.routes.ts`
+
+### Build Dependencies
 - Libraries must be built before being consumed by other projects
-- Use `ng generate` commands within library contexts for scaffolding
+- Demo application depends on built library artifacts in `dist/`
+- Use watch mode (`ng build --watch`) for development iterations
+
+### Library Development
+- All libraries use Angular 19.2+ with strict TypeScript configuration
+- Use `ng generate` commands within library contexts for scaffolding  
 - Libraries are publishable to npm after building to `dist/` directory
-- Testing uses Karma with Jasmine framework
