feat(public): .md mirror for every route + /llms-full.txt aggregate

[mastermanas805]

What this does

LLMs and crawlers no longer have to parse HTML to consume the marketing site. Every public HTML route now has a parallel .md mirror at the same path with a .md suffix.

HTML route	Markdown mirror
/	/index.md
/pricing	/pricing.md
/for-agents	/for-agents.md
/status	/status.md
/docs	/docs.md (all 8 sections in one file)
/blog	/blog.md
/blog/<slug>	/blog/<slug>.md
/use-cases	/use-cases.md
/use-cases/<slug>	/use-cases/<slug>.md

A single aggregate /llms-full.txt (~361 KB) concatenates every markdown page with URL-keyed section separators, so an LLM that wants the entire site's text can fetch one file instead of 115.

Where the content comes from

• Blog posts: copy .content/blog/<slug>.md verbatim
• Use cases: copy .content/use-cases/<slug>.md verbatim
• Docs: concatenate .content/docs/*.md (ordered by frontmatter order) into a single /docs.md
• React-only pages (home, pricing, for-agents, status): copy authored .content/pages/<name>.md (4 new files added to InstaNode-dev/content in commit 5fea532)
• Index pages (/blog, /use-cases): generated at build time from the directory listings + frontmatter

Link convention

All internal links in the markdown use the .md mirror (/use-cases/foo.md), not the HTML route (/use-cases/foo), so an LLM following links stays in markdown.

GitHub descriptions updated

Both repos now advertise the LLM-friendly URLs in their description:

• InstaNode-dev/content: "...LLM-friendly: https://instanode.dev/llms.txt · every page has a /.md mirror · full text at /llms-full.txt"
• InstaNode-dev/instanode-web: similar

Verification

• npm run build ✓ — 115 HTML + 115 .md + llms.txt + llms-full.txt (~361 KB, 115 sections)
• dist/index.md is the 2.5 KB homepage in markdown
• dist/docs.md is the 5.5 KB single-page docs (8 sections concatenated)
• dist/blog.md, dist/use-cases.md are generated indexes with markdown links
• dist/use-cases/ephemeral-test-database-for-a-risky-migration.md is the verbatim content-repo source
