Handle YAML frontmatter in Markdown preview

[PaulRBerg]

I add custom YAML frontmatter to my plan files (using a hook). The frontmatter looks bad on Plannotator UI:

Hey @PaulRBerg! Thanks for reporting this.

We've implemented a fix that renders YAML frontmatter as a styled metadata card at the top of the plan, rather than showing it as raw text.

What it looks like now:

• Frontmatter is parsed and displayed in a clean card with a muted background
• String values show as key-value pairs
• Arrays (like tags) render as colored pill badges

This will go out in the next release. If you'd prefer a different approach (e.g., hiding frontmatter entirely, different styling, etc.), let us know and we can adjust before the release ships!

Fixed in #45
