build-aarch64-linux.sh builds -p qbz-qt natively with the distro's Qt
(gated at >= 6.8, the tree's floor; Debian 13 / Ubuntu 25.04 / Fedora
41 qualify), installs rustup when absent, forces one rustc at a time on
<= 4 GB boxes, and runs the same offscreen smoke as CI. Its CROSS mode
is retired honestly: cxx-qt runs the target Qt's qmake during the
build, which cross-rs's Ubuntu 20.04 images cannot do. The qbzd script
and Cross.toml keep cross-compiling the daemon, with the Qt-free dep
set.

cross 0.2.5's default aarch64 image is Ubuntu 16.04 (xenial): libfreetype-dev
doesn't exist there (it's libfreetype6-dev) and its OpenSSL 1.0.2 / archived
repos break modern deps. Pin the :main image (Ubuntu 20.04+) and use the
libfreetype6-dev name (valid on both).

Native (on an ARM runner: apt deps + cargo build -p qbz) and cross (from
x86-64 via cross + Cross.toml arm64 sysroot) paths, auto-selected by host
arch. Documents the ~30 GB qbz_ui RAM wall (8 GB Macs / 4 GB Pis cannot build
natively). Cross path is best-effort/untested pending a first run.
