Shape carried by the widgets context. Adapters expose this through
a ContextPort<WidgetsContextShape> so the dispatcher can read
the active widget map without binding to the host framework's
context system.
Mirrors the value carried by the React adapter's WidgetsContext
(defined in react/SchemaComponent.tsx) — an optional
WidgetMap. The undefined branch signals "no scoped widgets
for this subtree; fall through to per-instance widgets, then the
global registry, then the resolver".
