v0.24.0 — Ceph + SDN deep: 603 → 715 tools

The hyperconverged release. The full Ceph plane (42 tools: OSD/mon/mgr/mds
lifecycle, pools, CephFS, flags, config, crush — destroy plans cite Ceph's own
cmd-safety verdict) and the deep SDN surface (70 tools: controllers, DNS, IPAMs,
fabrics, vnet-scoped firewall, IP mappings, prefix-lists, route-maps — with SDN
dry-run, the global lock handled as a never-ledgered capability token, and
rollback as a real undo for staged SDN config). Honest state: both new planes are
schema-built and mock-tested (9,182 tests), not yet live-proven — per-tool
docstrings say which is which. Adversarial review ran on every chunk and found
real defects every time; all fixed pre-release, review records in repo history.
