mermaid diagrams

sublimated supports mermaid diagrams in two ways:

embedded in markdown (planned)

mermaid code blocks in markdown will be supported:

```mermaid
graph LR
    A[start] --> B[end]
```

not yet implemented. when ready, will render server-side via Selkie at push time — no client-side mermaid.js.

standalone .mmd files

create a .mmd or .mermaid file with mermaid syntax. sublimated renders it server-side on push — no JavaScript needed in the browser.

see the mermaid docs for supported diagram types, how it works, and a demo file.
