Merge branch 'feature/frontend-hierarchy-components'

- Create reusable UI components: Badge, Breadcrumb, Card, DataTable,
  FilterChip, Pagination, SearchInput, SortDropdown
- Update Home page with search, sort, filter, and pagination
- Update ProjectPage with package stats, format filtering, keyboard nav
- Update PackagePage with DataTable for tags, copy artifact ID, metadata
- Add TypeScript types for paginated responses and list params
- Update API client with pagination and filter query param support
- URL-based state persistence for all filter/sort/page params
- Keyboard navigation (Backspace to go up hierarchy)
