docs: remediate T78 CLI capability migration contract (review deltas)

Applies the docs-delta review dispositions: frontmatter and header flip to
active with implementation held by M0, merge-invariant authority statement,
PRD trunk-scoped contract label, SITEMAP qualifier swap, brain/fleet-comms
provenance scoping for the registry-freeze citations, and removal of the
four trailing-space hard breaks (ranged diff --check now clean). Docs-only.
