Build Ubuntu 20.04 and 24.04 DEB artifacts in release-specific job
containers with explicit kernel headers.
Publish one bundle per Ubuntu LTS target and keep the README independent of
matrix versions.
Use normalized RPM matrix kernel versions in rolling snapshot archive
names. Keep vendor suffixes in package metadata and leave Ubuntu DKMS
independent of the runner kernel.
Publish a rolling prerelease after the complete master package
matrix succeeds. Validate and bundle every downloaded artifact before
replacing the previous master-rpm snapshot.
