Same dlopen as the snap stages for: the runner has e2fsprogs but not
the lib, and the first cold pull would fail. The t64 name with a
fallback keeps it honest if the runner image changes base.
The T6 run boots from a block device now; an engine without the blk
feature fails the lookup for krun_add_disk and the audit never sees a
machine. Same feature set as the snap ships.
The test has been declared as CI-only since it landed and never ran
anywhere. The job builds the engine from the tag the snap bundles,
takes libkrunfw from the pool, opens /dev/kvm, and runs the ignored
test with ECROU_BIN and LD_LIBRARY_PATH pointed at them.
Testing runs the pre-commit trio on pushes to main and PRs.
Releasing builds the snap on plain vX tags and publishes it to the
stable store channel; rc tags fail the version gate and leave the
publish job skipped.
