Pull request overview

Adds support for “RFM” (GitHub-alert-style) Markdown constructs alongside the existing legacy --- block --- RPF syntax, enabling blockquote markers like [!HINT], [!TASK], etc., and fenced code metadata to be parsed into existing RPF HTML components.

Changes:

• Introduces an RFM parser extension that recognizes [!MARKER] blockquotes and RPF-metadata fenced code blocks.
• Adds a tree pass to group adjacent RFM hints into a single legacy “hints panel”.
• Extends the HTML converter and test fixtures/specs to cover the new RFM examples and behavior.
