feat(web): rebrand marketing site to Voculinux

Names, wordmarks, package and install references move to voculinux;
site domain to voculinux.com with renamed public assets. Layout keeps
Carbon spacing/type/motion discipline remapped to the house palette
(teal interactive, warm paper, system stacks, red reserved). Header
and footer gain Bongbetic attribution chrome linking hosted brand
assets; no brand binaries vendored. Engine copy states whisper.cpp as
guaranteed default, others as best-effort extras, remote API as
user-configured with audio leaving the machine. Nix page carries a
fork-status note (upstream flake installs Vocalinux).
