* refactor(docs-site): move the doc tooling out of tools/
The five doc scripts and their test exist because of Starlight: sidebar
order frontmatter, the rehype link convention, the built site, and the
Astro build itself. They now live under docs-site/scripts and
docs-site/test, next to the rehype plugins and the site tests, which
leaves tools/ Python-only. ESLint stops ignoring those two directories
and its script rules now target them; the Astro sources stay excluded.
* ci(docs): deploy the site from dev
main moves only by release fast-forward, so a docs deploy tied to it
would lag every doc change until the next release. Deploy on push to
dev instead; main receives the same tree later and needs no deploy.
