v2.3.3

Bug Fixes

• Fumadocs directive normalization — normalize_fumadocs_directives in post_processors.py maps LLM shorthand callout names (:::warn, :::error, :::success, etc.) to the valid fumadocs set (:::warning, :::danger, :::tip). Previously these rendered as raw text instead of styled callout boxes.
• Frontmatter description cleanup — fix_frontmatter_description strips trailing :: / ::: artefacts from the YAML description: field that the remark-directive plugin partially parses, corrupting the nav sidebar descriptions.
• Mermaid error boundary silent fallback — MermaidErrorBoundary in scaffold now returns null for broken diagrams instead of a visible error <pre> block, keeping pages noise-free. Source-level mermaid fixes (_fix_mermaid_diagram) remain in place as the primary guard.
