Introduce a small kernel path gated on data_capture.regression_smoke that writes known u32 samples to the capture device, plus a userspace regression test that opens /dev/vdg and checks for the format magic and those CBOR values. Wire the suite into the regression Makefile/Nix build and document a host-side decode example. Fixes ldos-project#283 Signed-off-by: Vedant Madane <6527493+VedantMadane@users.noreply.github.com>
