ci: trigger Node.js integration tests on KERNEL_REV / native changes

The merge-queue gate (merge-queue-nodejs) and the labeled-PR preview
(trigger-tests-pr) both classify a change as "driver changes" via a path
allow-list that omitted KERNEL_REV and native/. A PR whose only relevant
change is a KERNEL_REV bump (or a native/kernel/** binding change) was therefore
detected as "no driver files changed" and auto-passed the required
"Node.js Integration Tests" check WITHOUT running anything — i.e. the kernel
integration suite was skipped for exactly the PRs that swap the pinned kernel.

driver-test already builds the napi binding from the driver's KERNEL_REV at the
dispatched commit, so once these changes trigger a dispatch the merge-queue run
exercises the integration tests against the pinned kernel version. Add native/
and KERNEL_REV to both detectors so kernel bumps are gated.
