Add Motion: the go-to-market operating system on top of the ledger

The ledger answers which contracted capacity is sold, to whom, at what
margin. It says nothing about the motion — the repeatable practice that
turns a customer conversation into a scoped deployment, and turns that
deployment into something the next one reuses.

Motion is deliberately not a parallel entity tree. DEMAND_STAGES already
is the motion, so Motion binds reusable artefacts to the stages of a
demand deal that already exists: an engagement hangs off one deal,
cascade deleted, one per deal by unique constraint.

Nine closed kinds, each declaring which stages it serves, and a starter
library of twelve templates covering all eight open stages.
