LabyricornandClaude Opus 5 d5d7091289 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.
