## 🌟 What's New

### 📋 Metadata Management System
Transform your markdown publishing workflow with automatic metadata management:

- **📝 YAML Front-matter**: Automatically inject publication metadata into your markdown files

- **🔗 Smart Link Management**: Seamlessly convert between local markdown links and Telegraph URLs

### 🚀 Enhanced Publishing Experience

**Before (v1.0.x):**
```bash
telegraph-publisher publish -f article.md -a "Author"
```

**Now (v1.2.0):**
```bash
# Enhanced publishing with dependency resolution
telegraph-publisher pub -f article.md -a "Author"

# Analyze your content structure
telegraph-publisher analyze -f article.md --show-tree

# Check publication status
telegraph-publisher status -f article.md
```

## 🎯 Key Features

### 1. **Automatic Dependency Resolution**
```markdown
# main.md links to intro.md and conclusion.md
telegraph-publisher pub -f main.md -a "Author" --with-dependencies
# ✅ Automatically publishes intro.md and conclusion.md first
# ✅ Replaces local links with Telegraph URLs in published content
# ✅ Updates main.md with metadata
```

### 2. **Smart Republishing**
```yaml
# Automatically added to your markdown files
---
telegraph_url: "https://telegra.ph/Your-Article-01-19"
telegraph_path: "Your-Article-01-19"
published_date: "2025-01-19T10:30:00Z"
author: "Your Name"
last_updated: "2025-01-19T10:30:00Z"
---
```

### 3. **Bidirectional Link Management**
- **Publishing**: Local links → Telegraph URLs in published content
- **Source Files**: Telegraph URLs → Local links in your markdown files
- **Consistency**: Keep your source files clean while published content works perfectly

### 4. **Configuration Management**
```bash
# Set up default preferences
telegraph-publisher config --username "Your Name"
telegraph-publisher config --max-depth 5
telegraph-publisher config --show

# Project-specific settings in .telegraph-metadata-config.json
{
  "defaultUsername": "Your Name",
  "autoPublishDependencies": true,
  "manageBidirectionalLinks": true,
  "maxDependencyDepth": 5
}
```
