ParallaxMD v0.1.1: Web Demo & UI Refinements

Fixed

• Reverted visual editor task lists to gracefully fallback to standard bullet strings to resolve underlying Milkdown checkmark DOM-syncing issues.
• Addressed Tailwind CSS typography plugin specificity conflicts.

Changed

• Replaced the three separate Title Bar theme buttons with a single unified light/dark toggle component.
• Added the ParallaxMD logo icon directly to the Title Bar next to the application text.
• Added a new Editor Shortcuts reference table detailing Visual Editor combinations (Ctrl+B, etc.) to the Markdown Cheatsheet.
