kernel-module-glowforge and python3-gfhardware are now pushed and pinned by
SRCREV in meta-openglow (no AUTOREV anywhere), and the meta-openglow
Scarthgap port is published on its scarthgap branch. Record the full
push/release sequencing in kas/README.md (incl. the release-time flip to the
pinned-remote meta-openglow block and the release-asset naming rule), and
commit the kas lockfile pinning poky/meta-openembedded/meta-freescale(-distro)
at the revisions the working build used.
The untracked kas/externalsrc-dev.yml overlay (local python3-gfhardware via
/mnt/c) is removed: the pinned SRCREV replaces it.
