Implements the bounded Spec 421 Entra comparable/renderable pack on the existing Coverage v2 operator surface.
- Adds typed Conditional Access normalization, comparison, and render summaries
- Keeps Security Defaults and other optional Entra types deferred until evidence-backed
- Preserves the existing Coverage v2 surface with claim-guard and redaction hardening
- Includes focused unit, feature, and browser coverage already recorded in the implementation report
Validation is documented in `specs/421-entra-core-comparable-renderable-pack/implementation-report.md`.
