feat(baoyu-markdown-to-html): pass through all rendering options from CLI

- CLI now supports --color, --font-family, --font-size, --code-theme, --mac-code-block, --line-number, --count, --legend
- convertMarkdown accepts full CliOptions instead of limited subset
- Dynamic help text showing available theme/color/font options
