Each infra VM now boots its own rootfs instead of a shared combined image, so
the exposed gateway VM no longer carries buildah + the control-plane code it
never runs (a fatter, less-isolated exposed surface — the opposite of the plane
split's intent). The combined image bought only "one artifact"; each VM already
kept a full copy of the shared rootfs, so nothing was saved at boot.
* orchestrator rootfs — control plane + buildah (Dockerfile.orchestrator.fc,
FROM orchestrator); the slim gateway rootfs boots bot-bottle-gateway:latest
directly. Dockerfile.infra.fc (the combined image) is deleted.
* `_infra_init` splits into `_orchestrator_init` / `_gateway_init` (shared
preamble via `_init_head`); each per-plane rootfs bakes only its role init,
so the `bb_role` cmdline branch is gone.
* infra_artifact is role-parametrized: a per-role package
(bot-bottle-firecracker-<role>), version hash, URL, cache dir, and candidate
subdir. `ensure_built` pulls both; `_expected_version` combines both markers.
* publish_infra builds the images once, then builds + publishes an
orchestrator and a gateway artifact under DIR/<role>/.
coverage.sh's candidate-dir plumbing is layout-agnostic (publish_infra --output
now fills DIR/<role>/, which ensure_artifact_gz reads). Full suite green.

Address PR #395 review (two P1s):
- Version hash covered only `bot_bottle/**.py`, but the image `COPY`s the
whole package — non-Python inputs baked in (egress_entrypoint.sh,
netpool.defaults.env) didn't change the version, so a launch host could
boot a stale rootfs whose code differs from its checkout. Hash every
regular file under bot_bottle/ (excluding __pycache__/.pyc). Regression
tests: a shell-script change bumps the version; .pyc/__pycache__ don't.
- publish_infra `_put` read the whole (hundreds-of-MB) gz into memory via
read_bytes(). Stream it from disk with an explicit Content-Length; the
tiny .sha256 stays in-memory. Test asserts the body is the file object,
not bytes.
