New crates/clawdie binary. Discovers a host's ZFS layout and provisions the
clawdie service, cross-platform via a Platform backend (FreeBSD rc.d + native
ZFS; Linux systemd + ZFS-on-Linux).
- discover: read-only OS + pool/dataset inspection
- plan: render the ZFS layout + service-install steps (dry-run)
- apply: executes the plan, and only with --yes (dry-run otherwise)
apply writes to disk only with --yes. Discovery + plan logic is unit-tested (7);
the disk-touching path must be validated on real hosts.
