feat(core-shared): extend wireUseCase with analytics arg and Analyzed brand propagation

Add AnalyticsProtocol to bind-protocols, extend WireUseCaseOptions with
optional analytics field, and compose the __analyzed brand inline in
wireUseCase (innermost, before withAudit) when analytics is provided.

Propagate __analyzed through withCapture and withSpan PROPAGATED_BRANDS
so the outermost container binding carries the brand for boot-time
assertion checks (Story 05).
