1. **AdminLayout.tsx** - Major changes:
   - Added imports for `NavLink`, `useNavigate`, `BookOpenIcon`, `ListIcon`, `LogOutIcon`, `Button`, `useAuthStore`, `usePlatform`
   - Added navigation items array with book management and borrow management
   - Added admin layout with sidebar navigation, header with username, and logout functionality
   - Added responsive layout for desktop/mobile

2. **router/index.tsx** - Changes:
   - Removed placeholder components (`AdminBooksPage`, `AdminBorrowsPage`, `AdminIndexPage`)
   - Added imports from actual admin feature pages
   - Updated routes to use real admin layout and pages

This is clearly a **feat** (new feature) commit, adding admin layout with navigation and routing to real pages. The scope would be **admin** or **ui**.

The key changes are:
- Adding admin sidebar navigation with book/borrow management links
- Adding logout functionality with username display
- Replacing placeholder admin page components with real page implementations
- Integrating admin layout with the router

Let me write a concise commit message following the rules.","signature":"2099424a-0948-4423-a191-3c37d24e52ed"}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":25016,"cache_creation_input_tokens":0,"cache_read_input_tokens":0,"output_tokens":0,"service_tier":"standard"},"context_management":null},"parent_tool_use_id":null,"session_id":"bf312622-fae8-446d-8b67-c708b9d3a022","uuid":"50eb9e22-cc58-4b45-8f03-95386c522466"}{"type":"assistant","message":{"id":"2099424a-0948-4423-a191-3c37d24e52ed","type":"message","role":"assistant","model":"deepseek-v4-flash","content":[{"type":"text","text":"<commit>
