Subject: [PATCH] ci(release): publish linux-aarch64 artifacts

Add an aarch64-unknown-linux-gnu entry to the release build matrix using
the native ubuntu-22.04-arm runner (no cross-compilation), and extend the
Linux-only steps to cover both linux targets:

- GLIBC ceiling check now matches *-unknown-linux-gnu (ubuntu-22.04-arm
  ships glibc 2.35, same baseline as the x86_64 runner).
- "Install Linux package tooling" and "Create Linux distro packages" now
  gate on runner.os == 'Linux' instead of the x86_64 target only.

The packaging scripts already map aarch64-unknown-linux-gnu to arm64/aarch64
(deb_arch_for_target / rpm_arch_for_target), so this produces the full set
of linux-aarch64 artifacts: tar.gz, .deb (arm64) and .rpm (aarch64).

Verified natively on aarch64: cargo release build, tar.gz and arm64 .deb
packaging via the existing scripts.
