Native messaging for strictly confined browsers
summary
Enables native messaging for strictly confined Firefox snaps by adding an xdg-desktop-portal that exposes a D-Bus API to locate manifests, prompt the user, spawn native connectors and pass open file descriptors; Firefox is patched (~1,800-line diff) to use the portal when available. Ubuntu 22.04 ships the distro patch and the snap has working demos: GNOME Shell extension management and KeeperXC password autofill; upstream portal and Firefox changes are not fully merged yet and a manifest-install script is required for some snaps.
