+Adopt the AG-UI interrupt lifecycle for tool approvals, generic responses, and
+client-tool execution, with typed bound resolvers, atomic batches, and
+structured errors. Interrupts run ephemerally by resuming from the full client
+message history in a fresh child run — no persistence required.
+
+This changes native approval and client-tool streams from legacy custom events
+to snapshot-plus-`RUN_FINISHED` interrupt outcomes. Deprecated
+`pendingInterrupts`, `addToolApprovalResponse`, raw `resumeInterrupts`, and
+legacy event readers remain as limited compatibility surfaces for migration;
+`addToolResult` remains supported.
