Install one-liners still fetch the upstream script, so each install
entry point now says so plainly (Nix-page precedent): upstream
installs Vocalinux, not Voculinux, and fork release artefacts are not
published yet. Homepage xbps card no longer claims signed repository
data ships with every release while the packaging pipeline (#29) is
open. Also 'VocaHQ remote' -> 'Flatpak remote' on the install page.
