The catalogue moves to its own repository

Thirty modules the mesh builds, provisions and runs, as manifests — one
per module, flat under modules/. They were in mesh-control/examples/,
which framed the mesh's real modules as illustrations of a control-plane
package; they are neither examples nor the control plane's. The engine
that reads them stays in mesh-control; the data lives here, consumed as
a build source.

Answers the tier-4 question novox/hq ADR 0030 left open — where the
catalogue lives — in favour of one flat repository, which the drop of
domain grouping (seats, claims and tags instead) makes the right shape.
