Skip checkpoint lifecycle/migration tests in CI

leofang · claude · leofang · commit e9c03de152d4 · 2026-05-04T17:22:04.000Z
cuCheckpointProcessCheckpoint hangs on CI runners (ephemeral VM +
container), causing all CUDA 13.x test jobs to time out.  Skip the
tests that call into the checkpoint driver when the CI environment
variable is set.  Input validation tests still run everywhere.
