the /offscale route comment, and the store learns about ssh

The platform's own reference to offscale was one stale comment naming /headscale
as an example route pair. Everything else that matches "offscale" in src/ is a
test fixture using it as an example app name, or the bundled catalogue entry.

Re-synced the marketplace so the catalogue advertises the ssh dependency the
manifest now declares — which is the point of the sync being cheap to re-run: a
plugin's manifest changing is not a marketplace deployment.
