feat(visual): add the slice 4g challenge fixtures and reference exhibits

Fourteen visual challenge fixtures and the first visuals for reference exhibits A through D, all executing without a line of subject-specific renderer code — which is the claim slice 4g exists to test. A subject the engine needs special handling for is a subject the format cannot express. The standalone CLI validator no longer disagrees with the production one. It had been falling through to ERR_UNSUPPORTED_TARGET for every `visuals.*` binding target, so legal exhibits — including the committed minimal-visual fixture — failed the CLI while passing the runtime. The four section 8.1 visual target families are now recognized in both, and a test runs the CLI validator across every exhibit and challenge fixture so the two paths cannot drift apart again.
