Restore the 2025-11-25 task wire types that were removed together with the task feature: the task schemas and inferred types, task members of the request/result/notification unions, the task request-params augmentation, the tasks capability key, the isTaskAugmentedRequestParams guard, and RELATED_TASK_META_KEY. The task feature itself remains removed — servers do not advertise the tasks capability and inbound tasks/* requests receive -32601 — but the wire surface stays so SDKs interoperate cleanly with peers on the 2025-11-25 revision.
