Retire the build-time ramdisk packer and the packed initial-ramdisk.img.
make-fat-image.py now lays every user binary out at its FHS path on the
boot volume (system/services, system/drivers, system/tests), and the EFI
loader walks \system at boot, packing what it finds into an in-RAM v2
initial_ramdisk whose entry names are full FHS paths. init rides the
table like every other binary: its dedicated handoff fields are gone and
the kernel spawns PID 1 via the same lookup as everyone else
(process.spawnBundled).
system_spawn resolves names by exact path first, then unique basename,
and normalizes argv[0] to the stored path — so task names (and, next,
the tagged log ring's attribution) are honest binary paths everywhere.
initrd v2 rejects the old magic so a stale image fails loudly.
Groundwork for per-process logging (/var/log/<boot-stamp>/<binary-path>.log)
and the kernel-VFS /system mount.
