The linux-image-amd64 postinst creates /vmlinuz but the paired
/initrd.img symlink only shows up via an initramfs-tools hook that
doesn't fire when we call update-initramfs ourselves. Without it,
the top-level Makefile's `cp live-image/build/initrd.img` fails and
`make release` aborts with a broken bundle.

Two bugs chained together to ship a broken bundle:
1. With Bootable=no, mkosi skips update-initramfs, so no
/boot/initrd.img-<kver> ever gets generated inside the rootfs.
The postinst now runs update-initramfs via chroot to produce it.
2. The `make release` recipe chained its `cp` calls with `;`, so
a missing live-image/build/initrd.img silently failed and the
bundle still got tarred + uploaded. Adding `set -e` at the top
of the recipe makes any missing component fail the build loudly
instead of shipping a half-bundle.

mkosi was failing with "systemd-boot was not found at
usr/lib/systemd/boot/efi" because Bootable=yes expects systemd-boot
installed *inside* the image for EFI boot. This image is only ever
PXE-booted — iPXE loads vmlinuz+initrd from TFTP directly, so the
rootfs itself needs no bootloader.
Switching to Bootable=no drops the EFI-image assembly step; the
linux-image-amd64 postinst still creates /vmlinuz and /initrd.img
symlinks that the top-level Makefile copies into the bundle.

mkosi only mounts live-image/ as /work/src, so the postinst couldn't
reach the repo-root bin/vetting-agent.linux-amd64 — the build failed
in CI with `install: cannot stat '/work/src/bin/vetting-agent.linux-amd64'`.
The Makefile now copies the prebuilt agent into mkosi.extra/, which
mkosi merges into the image root automatically. The postinst is
reduced to creating the multi-user.target.wants symlink.

mkosi refuses to run a non-executable postinst. git was tracking it
as 100644 because it was added from Windows (no POSIX exec bit on the
FS), so CI saw a non-executable file even though WSL/Linux had been
treating it fine locally. Same fix applied earlier to install.sh +
pxe-setup.sh.

Collapses the LXC side of PXE enablement from a six-step manual dance
(build, fetch iPXE, scp, bridge, hand-edit yaml) into:
make release # dev box (Linux/WSL)
scp bundle.tar.gz lxc:/tmp/
sudo ./install.sh # base install, unchanged
sudo ./pxe-setup.sh --interface ... --dhcp-range ... --orchestrator-url ...
pxe-setup.sh fetches iPXE from boot.ipxe.org, verifies against pinned
SHA256s in deploy/ipxe-shas.txt (fail-closed), places vmlinuz/initrd.img
from the bundle, and rewrites only the pxe: block of vetting.yaml.
Idempotent; --force gates overwriting a hand-edited block.
Adds Supervisor.Validate() — called before dnsmasq spawn — so typo'd
configs fail at orchestrator startup with clear errors naming the
missing file or yaml key, instead of silently serving broken TFTP
until a real host tries to PXE-boot. Nine tests cover missing files,
bogus interface, malformed dhcp_range, bad orchestrator_url, and
aggregate reporting.
Hypervisor bridge creation stays documented (LXC can't do it) but
everything downstream of the bridge is now scripted.
