📛 docs: badges on the README, and an install section that tells the truth

Five badges under the title: CI and Docs are live workflow badges (the Docs
one links to the deployed site), and Node, TypeScript and MIT are static,
tinted the brand brown from the landing page rather than shields' defaults.
No npm badge yet — the package is not on the registry, and a badge that
renders "not found" is worse than none. It gets added with the first publish.

The real fix hiding under the badges: Installation led with `npm install
cereale`, which does not resolve to this library — the name is unclaimed.
The section now says so and gives the clone/pack/install route the landing
page has carried since 0.4.0. Also synced the pins the page got and the
README missed (tsc 5.2+, Bun 1.3, NestJS 11.1), and the line describing the
docs site as "served from docs/ on main" now describes the Actions
deployment that replaced branch serving.
