feat(core-shared): add Analyzed brand check to assertFeatureConformance

Mirrors the existing Audited check: when a use case declares
analyticsEvents.length > 0 and the bound function lacks the __analyzed
brand, assertFeatureConformance throws ConformanceError at boot time.

Adds three synthetic conformance tests: passes when brand present +
events declared, throws naming Analyzed when events declared + brand
missing, passes when events empty + brand absent.
