Initrd Repack
just run automatically repacks the initrd before every boot. It cross-compiles guest binaries, injects them into the initrd, and capsem-init prefers initrd-bundled copies over rootfs copies at boot. This is the fast iteration loop (~10s) -- no full rootfs rebuild needed for guest binary changes.
