directAppUrl(), the legacy open() path, and resolveRuntimeLaunchUrl()
now upgrade to https only for ports the app gate fronts — decided from
the signed catalog's embedded manifest ports (auth gated/open), so
plain-HTTP publishes (legacy installs, auth:none API ports like
Cuprate's RPC) keep http instead of failing outright. fetchAppCatalog()
merges the daemon-verified signed catalog into the App Store listing
(signed entries appear immediately; community copy supplies featured
and curated metadata), and Marketplace.vue uses the same dynamic fetcher
as Discover so the grid sees signed-new apps too.
