Generate markdown files and llms.txt during build

[rgbkrk]

Add parallel markdown renderers that mirror React components to generate static .md files for each page alongside HTML. Build now runs markdown generation after Next.js build, producing:

• llms.txt - Overview table with all kernels and scores
• llms-full.txt - Complete conformance data concatenated per-kernel
• index.md - Summary matrix
• kernel/*.md - Per-kernel detail pages (17 files)

Renderers reuse data transformation logic from report.ts helper functions for consistency.
