Ryan Malloy 3b505644b2 Kernel release 6.18.38-rt-cuckoo+: reproducible build, guarded installer
Rebuilt with KBUILD_BUILD_USER/HOST/TIMESTAMP pinned. Without them the kernel
bakes the builder's user@hostname and wall-clock build time into /proc/version,
which publishes operator identity in a public artifact and makes the build
unreproducible. Pinned, anyone can rebuild and diff the bytes — the only trust
story available for an unsigned community kernel.

The installer refuses to run on anything but a Pi 4, refuses a mismatched
image/modules pair (vermagic failure means no /dev/pps0 on a kernel that
otherwise boots fine — silent and miserable to debug), verifies SHA256SUMS,
never touches kernel8.img, and leaves rollback as deleting one config.txt line.

Boot-tested on the Pi: Stratum 1, 273 ns offset, PPS handler confirmed NOT
threaded. Binaries ship as release assets, not in git.
