The install dialog folds a registry control beside the guide: the
official registry, the mirrors the Host configured, and a typed
address, remembered in this browser and passed to the check and the
run. The installing screen names the registry the Host moved on to,
each pnpm run carries its registry, and a failed run names every
registry asked, or the host a git or tarball spec could not reach,
with a shortcut back to the registry options. The Host answers the
spec's own host and the registries it asked so the dialog can say so.
Also documents the registry plan in the package READMEs, the boot
subsystem page, the catalogs, and an Agent Note; pins the flow through
a real Host/browser e2e and refreshes the tool-schema snapshots.
