v2.3.4

Bug Fixes

• Bare mermaid fence repair — fix_bare_mermaid_fences in post_processors.py detects when the LLM writes mermaid as a bare paragraph instead of opening a ```mermaid fence, and inserts the correct fence. Without this, {node} labels inside diagrams leak into free MDX body and cause acorn parse errors.
• Leaf card directive fix — fix_leaf_card_directives converts LLM-generated ::card{...}\nCONTENT\n:: blocks to :::card{...}\nCONTENT\n::: container directives that the fumadocs remark plugin actually understands. Previously the standalone :: close markers rendered as visible text on the page.
