Introduces a plugin-style RendererRegistry that replaces the monolithic
switch statement in app.js. Each file type is now a self-contained
renderer module in public/renderers/.
New renderers:
- registry.js — central RendererRegistry (window.RendererRegistry)
- html-renderer.js — sandboxed iframe for .html files
- react-renderer.js — Babel JSX → ReactDOM render for .jsx files
- svg-renderer.js — inline SVG with script-tag sanitisation
- json-renderer.js — interactive collapsible tree view for .json
- mermaid-renderer.js — Mermaid diagram rendering for .mmd/.mermaid files
- markdown-renderer.js — marked.js + hljs; detects ```mermaid blocks
- python-renderer.js — rich "click Run" preview for .py files
- yaml-renderer.js — hljs-highlighted view for .yaml/.yml files
- text-renderer.js — catch-all fallback (priority 0)
Adding a new renderer only requires:
1. Create public/renderers/<name>-renderer.js
2. Call RendererRegistry.register({ name, extensions, render })
3. Add a <script> tag in index.html
Also adds marked.js and Mermaid.js CDN imports, JSON tree viewer CSS,
and full Markdown body styles.
