chore: move the archive-fetching tooling out of this branch

The fetching scripts and their docs now live on the `tooling` branch, which
is not published to GitHub. This removes the two references that would
otherwise dangle here: the `jd2` npm script and the CLAUDE.md bullet
describing it.

The viewer's own gallery-dl support is untouched and stays here —
src/lib/gallery-dl-sidecar.ts and friends parse sidecars at display time and
are app code, not tooling.
