feat: implement md-render command with client-side JavaScript rendering - Issue #132

Add comprehensive client-side markdown rendering functionality with dark theme support:

Core Features:
- md-render command generates self-contained HTML files
- Embedded markdown payload with client-side JavaScript rendering
- marked.js integration from CDN with graceful fallback
- YAML front matter support and title extraction

Template System:
- 4 responsive templates: basic (default), github, academic, dark
- Dark theme with GitHub dark mode inspired colors
- Custom CSS injection capability
- Mobile-responsive design with viewport support

Implementation Details:
- Complete TDD8 workflow: ISSUE→TEST→RED→GREEN→REFACTOR→DOCUMENT→REFINE→PUBLISH
- 11+ comprehensive test scenarios with excellent coverage
- Refactored template system using style dictionaries
- Enhanced CLI help text with usage examples
- Clean code organization and documentation

Usage:
  markitect md-render README.md --template dark
  markitect md-render article.md --template github --css custom.css

Generate HTML with client-side JavaScript markdown rendering.
Creates a self-contained HTML file that includes the markdown content
as JavaScript data and renders it in the browser using client-side
markdown parsing with marked.js.
The generated HTML includes:
• Embedded markdown content as JavaScript payload
• Client-side rendering with marked.js from CDN
• YAML front matter support and metadata extraction
• Multiple responsive template options
• Custom CSS injection capability
• Graceful fallback if JavaScript fails
INPUT_FILE: Path to the markdown file to render
Available Templates:
• basic (default) - Clean, minimal design with system fonts
• github - GitHub-style appearance with heading underlines
• academic - Academic paper style with serif fonts and justified text
• dark - GitHub dark mode inspired theme with dark background
Examples:
# Basic usage with default template
markitect md-render README.md
# Specify output file and template
markitect md-render README.md --output index.html --template github
# Dark theme for night reading
markitect md-render docs/guide.md --template dark
