Add conditional operating-model judge

[theclaymethod]

Summary

• add an isolated operating-model verifier that routes each slide or coherent page section to none, relational, operating-model, or simulated-surface
• judge model fidelity only when relationships are load-bearing; simple covers, heroes, quotes, FAQs, and one-claim units are explicitly exempt
• activate the pass for decks, fixed presentation stages, and sectioned long-form pages while leaving simple pages unchanged
• add clean/fire verdict fixtures plus a 16-case routing set covering slides, sections, and all four treatments
• deduplicate React across external source trees during export, preventing a null hook dispatcher at runtime
• align React and ReactDOM on exact version 19.2.7 and add a regression test for exported React singleton behavior
