Improve current document highlighting with better URL matching

- Add removal of previous highlighting before applying new one
- Support multiple URL matching strategies (exact, full URL, ends with)
- Add debug logging to troubleshoot highlighting issues
- Reset all links before applying highlight to ensure clean state

+## 本番環境へのデプロイ
+
+### ⚠️ 重要: サブドメインを使用してください
+
+このアプリケーションは **サブドメイン** でのデプロイを推奨します。
+
+```
+✅ 推奨: kb.example.com
+❌ 非推奨: example.com/kb （サブディレクトリ）
+```
+
+**理由**: Livewire 3はサブディレクトリデプロイに完全対応していません。`/livewire/update` エンドポイントがサブディレクトリを考慮しないため、AJAX通信が失敗します。
+
+### デプロイ手順
+
+1. **サブドメインのDNS設定**
+   ```
+   kb.example.com → サーバーIPアドレス
+   ```
+
+2. **Webサーバー設定**（nginx例）
+   ```nginx
+   server {
+       listen 80;
+       server_name kb.example.com;
+       root /var/www/knowledge-base/src/public;

-## About Laravel
+## Features
 
-Laravel is a web application framework with expressive, elegant syntax. We believe development must be an enjoyable and creative experience to be truly fulfilling. Laravel takes the pain out of development by easing common tasks used in many web projects, such as:
+### Core Functionality
+- **Markdown-based documents** with live preview using EasyMDE editor
+- **Wiki-style linking** with `[[Document Title]]` syntax
+- **Automatic backlinks** - see which documents reference the current page
+- **Folder organization** - use `/` in titles to auto-organize into folders (e.g., `Laravel/Livewire/Components`)
+- **Quick switcher** - Press `Ctrl+K` to instantly search and navigate
+- **Full-text search** - MySQL FULLTEXT index with ngram tokenizer for multilingual support
+- **ID-based routing** - Clean URLs with guaranteed uniqueness
 
-- [Simple, fast routing engine](https://laravel.com/docs/routing).
+### Multi-Language Support
-- [Powerful dependency injection container](https://laravel.com/docs/container).
+Interface available in **16 languages**:
-- Multiple back-ends for [session](https://laravel.com/docs/session) and [cache](https://laravel.com/docs/cache) storage.
+- English, 日本語 (Japanese)
-- Expressive, intuitive [database ORM](https://laravel.com/docs/eloquent).
+- 简体中文, 繁體中文 (Simplified/Traditional Chinese)
-- Database agnostic [schema migrations](https://laravel.com/docs/migrations).
+- 한국어 (Korean)
-- [Robust background job processing](https://laravel.com/docs/queues).
+- हिन्दी (Hindi), Tiếng Việt (Vietnamese), Türkçe (Turkish)
-- [Real-time event broadcasting](https://laravel.com/docs/broadcasting).
+- Deutsch, Français, Español, Português (Brasil)
+- Русский, Українська, Italiano, Polski
 
-Laravel is accessible, powerful, and provides tools required for large, robust applications.
+Language preferences persist for both authenticated and guest users via cookies.
 
-## Learning Laravel
+### Responsive Design
+- **Mobile-first** interface with hamburger menu
+- **Tablet and desktop** optimized layouts
+- **Touch-friendly** navigation
+- All features work seamlessly across devices
 
-Laravel has the most extensive and thorough [documentation](https://laravel.com/docs) and video tutorial library of all modern web application frameworks, making it a breeze to get started with the framework. You can also check out [Laravel Learn](https://laravel.com/learn), where you will be guided through building a modern Laravel application.
+### User Management
+- **Role-based access** - Admin and regular user roles
+- **User authentication** - Laravel Breeze integration
+- **Profile management** - Update name, email, password, and language preference
 
-If you don't feel like reading, [Laracasts](https://laracasts.com) can help. Laracasts contains thousands of video tutorials on a range of topics including Laravel, modern PHP, unit testing, and JavaScript. Boost your skills by digging into our comprehensive video library.
+## Technology Stack
 
-## Laravel Sponsors
+- **Backend**: Laravel 12.0 (PHP 8.2+)

+└── routes/

+```
+
+## Key Concepts
+
+### Document Organization
+
+Documents are organized using **virtual paths** derived from titles:
+
+```php
+Title: "Laravel/Livewire/Components"
+→ Path: "Laravel/Livewire/Components.md"
+→ Slug: "components"
+→ Sidebar: Nested under Laravel → Livewire → Components
+```
+
+No manual directory field needed - just use `/` in the title!
+
+### Wiki-Style Links
+
+Create links between documents using double brackets:
+
+```markdown
+See [[Getting Started]] for more information.
+Links to [[Uncreated Pages]] appear in red.
+```
+
+Links are automatically:
+- Extracted and stored in the `document_links` table
+- Rendered as clickable HTML anchors
+- Displayed as backlinks on target documents
+
+### ID-Based Routing
+
+URLs use document IDs instead of slugs:
+
+```
+/documents/123        (instead of /documents/my-document-slug)
+```
+
+Benefits:
+- Guaranteed uniqueness
+- Title changes don't break URLs
+- Simpler route model binding
+
+### Folder State Persistence
+
+Sidebar folder expanded/collapsed state is stored in `localStorage`:
+
+```javascript
+// Managed by Alpine.js
+localStorage.getItem('kb_expanded_folders')
+// ["Laravel", "Laravel/Livewire", "Docker"]
+```
+
+Survives page navigation and browser sessions.
+
+## Customization
+
+### Adding new languages
+
+1. Add to `SetLocale::SUPPORTED_LOCALES` in `app/Http/Middleware/SetLocale.php`
+2. Create translation file at `lang/{code}/messages.php`
+3. Copy structure from existing language file
+
+### Changing default locale
+
+Edit `config/app.php`:
+
+```php
+'locale' => 'en',  // Change to your preferred language code
+```
+
+### Customizing markdown styles
+
+Edit `resources/css/app.css`:
+
+```css
+@layer components {
+    .prose .wiki-link {
+        @apply text-indigo-600 hover:text-indigo-800 underline;
+    }
+}
+```
+
+## Troubleshooting
+
+### Livewire assets not loading
+
+```bash
+docker compose exec php php artisan livewire:publish --assets
+```
+
+### Frontend changes not reflecting
+
+```bash
+npm run build
+docker compose exec php php artisan view:clear
+```
+
+### Database connection errors
+
+Check `.env` file matches Docker Compose settings:
+
+```env
+DB_CONNECTION=mysql
+DB_HOST=kb_mysql
+DB_PORT=3306
+DB_DATABASE=knowledge_base
+DB_USERNAME=kb_user
+DB_PASSWORD=kb_password
+```
+
+### Alpine.js errors in console
+
+Ensure scripts are loaded in correct order in `knowledge-base.blade.php`:
+1. Livewire scripts first
+2. Alpine.js initialization (via Vite)
+3. Custom Alpine components
