Markdown Midget v0.1.6-alpha1

Added

• Mermaid diagrams. Fenced code blocks tagged mermaid now render as live diagrams in the WYSIWYG view (flowcharts, sequence diagrams, class diagrams, etc.). The diagram appears below the block, the source itself is hidden while the cursor is outside the block, and revealed for inline editing when the cursor moves into it. Markdown round-trips unchanged (the on-disk file remains a normal ```mermaid fence). Print and PDF export render the diagram (not the source), with page-break-inside avoided.

Known limitations

• Mermaid pulls a large dependency tree (D3, dagre, cytoscape) — the editor bundle grows from ~560 KB to ~3.9 MB. The extracted bundle is one-time-per-run and cached by WebView2 thereafter; the app's startup time is still well under a second on a typical machine, but the on-disk .exe size grows by about 3.5 MB after compression. Bundle splitting / lazy-load is a possible later optimization if this becomes a concern.

See CHANGELOG.md for full history.
