Placeholder v0.0.0 — the canonical home for this crate will be
`https://github.com/aegis-boot/aegis-boot` once the GitHub org
transfer (see `docs/governance/ORG_MIGRATION_PLAN.md`) completes.
A real release will ship under a future non-0.0.0 version. If you
depend on this placeholder, pin to a later version once the real
crate lands; the 0.0.0 placeholder is here purely to reserve the
name and prevent squatting during the repo transition.
