feat(site): split llms.txt into per-framework and blog sub-indexes

[decepulis]

Closes #695

Summary

Split the monolithic llms.txt index into a hierarchical structure so LLMs can fetch only framework-relevant documentation instead of the entire site catalog.

Changes

• Root llms.txt now links to per-framework sub-indexes (/docs/framework/{fw}/llms.txt) and a blog sub-index (/blog/llms.txt) instead of listing every page
• Per-framework docs sub-indexes group pages by their data-framework attribute
• Blog gets its own sub-index with newest-first ordering preserved
• Sub-index URLs added to sitemap customPages
• Extracted PageEntry interface to replace repeated inline type annotations

Implementation details

The single generateLlmsTxt() function was replaced by three focused generators:

• generateRootIndex() — links to sub-indexes and lists other pages
• generateDocsIndex() — framework-specific docs listing
• generateBlogIndex() — blog posts sorted newest-first

Framework is determined by the existing data-framework attribute already set on docs pages.

Testing

pnpm build:site — verify the generated llms.txt, blog/llms.txt, and docs/framework/{html,react}/llms.txt files in dist/

Entry Breakdown

Subpath sizes are the additional bytes on top of the root entry point, measured by bundling root + subpath together and subtracting the root-only size.

ℹ️ How to interpret

Sizes are minified + brotli, measured with esbuild.
Package totals are computed as root size + marginal subpath costs.
Subpath marginal cost = (root + subpath bundled together) − root alone.

✅	No change
🔺	Increased ≤ 10%
🔴	Increased > 10%
