 * adds OpenAIThinkingHandler — append-only as new providers ship.
 *
 * Future provider authors:
 *   • Implement `ThinkingHandler` for your provider
 *   • Append to this array
 *   • The shared contract test in `test/thinking/contract.test.ts`
 *     verifies your handler honors the framework's invariants
