Android was the one app that could open a punktfunk:// link but never hand
one out, so every Android link had to be typed by hand — and the host's
stable record id, which is the part that keeps a link working after the box
changes address, isn't shown anywhere in the UI to type.
Both homes now offer Copy link: the touch grid's card overflow menu, and the
controller home's host options (Up on a tile). A pinned card copies its own
profile with it, matching Linux and Apple; a host card copies none and so
keeps honouring the host's binding, exactly like tapping it does.
The URL is the shared self-emitted form (DeepLinks.forHost), already covered
by the cross-language vector tests, so the three emitters stay in step.
Android 13+ draws its own clipboard confirmation and we add nothing on top of
it; below that we say so ourselves, as a toast in the console home, which
renders neither banner.
