v0.2.0

Migrate from PhantomJS to Puppeteer with modern CLI
Major rewrite to modernize the library:

• Replace PhantomJS with Puppeteer for better browser automation
• Modernize to ES6+ syntax (import, const, template literals, async/await)
• Update CLI interface:
  • URL is now positional argument
  • Output file uses -o/--output flag (default: screenshot.png)
  • Replace --call-phantom with --wait-for-selector for cleaner API
  • Unified --timeout for both page load and selector waiting
  • Add --verbose flag (silent by default)
  • Add --quality for JPEG output
  • Add --width/--height for viewport control
  • Remove unintuitive shortcuts (keep only -o and -s)
• Add JPEG output support with quality control
• Add .gitignore for node_modules and generated images
• Update README with real-world examples and modern usage
