New package: @fumadocs/local-html
A content source for local HTML files. It integrates externally-produced HTML pages (exported decks, reports, agent-generated deliverables) into a Fumadocs site, adapting them to the docs theme: content is scoped to <main>/<article>, page chrome and scripts/styles are dropped, class/style attributes are removed so prose styling takes over, and headings get generated ids for TOC and search indexing.
Code blocks are highlighted with Shiki, configured through rehypeCodeOptions like @fumadocs/local-md (false to skip it). The language comes from the block's language-* class, which now survives adaptStyles.
Hot reload works like @fumadocs/local-md: @fumadocs/local-html/dev/vite for Vite, or the bundled local-html dev server with @fumadocs/local-html/dev/ws for everything else.
