feat(compat): Profile, Gates und Pods über den Kompatibilitätskern

Neu: Tier, Profile, Compatibility, CapabilityLocked, CapabilityGate, CompatibilityComponent, ProvidesCompatibility, DiviProfile sowie PodsFeature, PodsCompatibility und PodsIntegration. Das CapabilityGate sperrt gesperrte und unbekannte Fähigkeits-IDs (übernimmt die Sperre unbekannter IDs vom DiviFeatureGate) und delegiert nur Divi ausdrücklich. Pods-Schema, -Lesen, -Schreiben und -Feldrechte laufen über usable(PodsFeature::…); Schreiben verlangt FieldRead und FieldWrite, damit ein Rollback keine Werte verliert. lit-site-status meldet Pods über die CompatibilityComponent.
