12-task implementation plan for the runtime boot-time check of the
conformance system. Reifies the phantom-type brands from milestone i as
non-enumerable runtime markers via Object.defineProperty, and ships
assertFeatureConformance(container, manifest, symbols, ctx) which walks
the manifest, resolves each use case from the feature's container, and
throws ConformanceError synchronously when a binding is missing a
required brand.
Per-feature self-assertion: each bindProductionX(ctx) calls
assertFeatureConformance at its tail, so the boot check runs once per
feature and is forward-compatible with future apps wiring those binders.
Also bundles the two forward-looking items the milestone-i reviewer
flagged (re-export authManifest from auth root barrel; TODO breadcrumb
in withAudit for future automation).
