CI / Lint + build + test (push) Has been cancelled
Automate PXE setup: release bundle + pxe-setup.sh + startup validation
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.

# Vetting live image
Debian-based Linux live image that PXE-booted hosts drop into. Runs the
`vetting-agent` binary under systemd and reaches back to the orchestrator
over HTTP+SSE.
## Preferred build path: `make release`
Run `make release` from the repo root (Linux/WSL) — it builds the live
image *and* bundles it with the orchestrator binary, install scripts,
and pinned iPXE SHAs into a single `vetting-bundle-<sha>.tar.gz`. See
[../docs/operations.md](../docs/operations.md) for the install flow.
## Manual build (dev loop)
On Windows:
```sh
wsl make -C live-image all
```
On Linux:
```sh
make -C live-image all
```
This produces `live-image/build/vmlinuz` and `live-image/build/initrd.img`.
`deploy/pxe-setup.sh` picks them up automatically when run from the repo
tree — no manual copy needed.
## iPXE binaries
The dnsmasq supervisor expects `ipxe.efi` and `undionly.kpxe` in
`pxe.tftp_root`. `deploy/pxe-setup.sh` fetches them from boot.ipxe.org
and verifies against pinned SHA256s in `deploy/ipxe-shas.txt`. Bumping
the pins requires a deliberate repo commit.
## WSL prerequisites (Windows dev)
```sh
sudo apt install mkosi debootstrap squashfs-tools dosfstools
```
