Feature Request: Support for Mermaid.js diagrams in Markdown #48

would like to suggest adding support for Mermaid.js diagram rendering within Helix. As a privacy-focused Markdown vault, having the ability to create flowcharts, sequence diagrams, and Gantt charts directly in our notes would significantly enhance the documentation experience.

Good timing! v1.2.9 ships exactly this, was already in the works alongside this issue. ```mermaid code blocks render with one click, and you can copy or save as an image.
