Adds boot-time check that every manifest-declared use case is bound
through withSpan (__instrumented) + withCapture (__captured), with
withAudit (__audited) enforced when audits[] is non-empty. Propagates
inner brands through withSpan so the outermost container-resolved
binding carries all brand markers.
