Fix
Coach replies render formatted, not raw markdown
When the Coach shared a full draft, its reply could show raw markdown — literal "##" headings and unrendered diagram code. Coach replies now render with proper headings, lists, tables, and diagrams, just like the draft view.
When the Thinkr Coach walked you through a full draft — a TL;DR, problem alignment, a technical design annex with diagrams — its reply could come back as raw markdown. You'd see literal ## in front of every heading and the diagram blocks printed as plain code instead of an actual chart.
The chat was only formatting the basics (bold, italics, inline code). Anything more structured passed straight through.
Now Coach replies render the same way your draft does: headings, bulleted and numbered lists, tables, code blocks, and Mermaid diagrams all come through formatted. The same fix applies everywhere the assistant chats with you — Coach, the notebook, and the Prototype and Proposal builders.
