- _build_runtime calls now chain across all middlewares before dispatch instead of being called per-middleware independently - create_agent accepts backend= (object|None); passed to AgentRuntime - AgentRuntime gains backend: object|None field + from_runtime param - ModelRequest drops duplicated fields; model/system_prompt/tools/etc are now properties that delegate to runtime, eliminating redundancy - _wrap_hook/_wrap_async_hook no longer take a mw argument
