Implement property-based invariant verification: - TestPropertyConfigHashAlwaysPresent: Valid configs produce non-empty hash - TestPropertyConfigHashDeterministic: Same config produces same hash - TestPropertyDetectionSourceAlwaysValid: CreateDetectorWithInfo returns valid source - TestPropertyProvenanceFailClosed: Strict mode fails on incomplete env - TestPropertyScanArtifactsNeverNilEnvironment: Artifacts can hold Environment - TestPropertyManifestEnvironmentSurvivesRoundtrip: Environment survives write/load Uses gopter for property-based testing with deterministic seeds
