A seventh pm target (linux-arm64-bionic) stages the TUR python3.11
.deb, the termux nodejs/uv .debs, and their runtime-lib deps into the
payload -- same pm-consumer shape as the desktop legs: pm owns the pin,
the hardened download (redirect-safe, retry-wrapped), the ar+tar
DebPackage extraction, and file-evidence verify for binaries the
staging host cannot execute.
