jschoubben 9cc3c1ac2a model-usage bed: prove the usage store end to end (ADR 0054)
A VM bed: a postgres provider and the model-usage consumer on one node, the
substrate on the other. A usage event injected into the mesh is upserted into
model-usage's provisioned store, asserted at both grains, latest-per-key, and
in the clear.

Also, in build-module-runtime.sh, add migrate/index.ts and pg.d.ts to the
compiled entrypoint set so a module may carry a run-once entry and an ambient
type declaration (model-usage uses the latter for the pg driver).

The bed surfaced and drove several fixes elsewhere: a short module slug for the
S3-key identity bound (ADR 0049), host-network containers getting the mesh's
names (mesh-control), and injecting the event from a publisher rather than the
pure-consumer store (its account has no publish right by design).

# The usage context store, proved end to end (novox/hq ADR 0054). A postgres PROVIDER and the
# model-usage CONSUMER ride one node; the substrate (store, broker, control) owns the other. As in
# two-node-db, the app-postgres provider and the mesh's own substrate store both want host port 5432,
# so they cannot share a machine — the substrate lives on `anchor` and NOTHING else, and `laptop`
# runs postgres plus model-usage. Provider and consumer are co-located on laptop, so only enrolment
# crosses to anchor, over the underlay both machines already share.
#
# The property the bed proves: a usage event emitted into the mesh is upserted into model-usage's
# provisioned postgres store, at BOTH grains (licence and session, differing only in `consumer`),
# LATEST-per-key, and IN THE CLEAR — an ordinary select returns the numeric value and its raw payload.
