fix(langchain): keep middleware-internal model calls off the `messages` stream `SummarizationMiddleware`, `LLMToolEmulator` and `LLMToolSelectorMiddleware` make their own model calls. With `stream_mode="messages"` those calls streamed their tokens as if the agent had said them: the summary text, the emulated tool output and the tool selection JSON. Only the `stream_events` v3 projection filtered them, through `InternalCallTransformer`. Tag each internal call `nostream`. langgraph's messages handler already skips runs with that tag, for `stream_mode="messages"` and for `stream_events` v3 alike. The calls keep their `lc_source` metadata and `lc_internal_call` marker, and stay visible in traces and in `astream_events`, now tagged `nostream`. A custom `summarizer` runs under the same tag, so model calls inside it stay off the stream too. With the tag in place the `InternalCallTransformer` registrations on these three middleware never receive an event, so they are removed. The transformer stays available to other middleware.

fix(langchain): redact `PIIMiddleware` output before it streams or persists With `apply_to_output=True` or `apply_to_tool_results=True`, `PIIMiddleware` redacted in `after_model` and `before_model`, one step after the model or tool node had already written the raw message. The raw text went out on the `messages`, `updates`, `values`, `checkpoints` and `tools` stream modes and stayed in a checkpoint, and the redacted copy never reached `messages` because it keeps the message id, which that mode has already seen. The middleware now also wraps the model and tool calls and redacts their results before anything is written, including the `ToolMessage`s in a `Command` or list that a tool returns. Model calls under the wrapper run with the `nostream` tag, set on the callbacks of the surrounding config, so it holds for any model runnable, for a model a later middleware swaps in, and for a model bound with its own tags. Tools run as a copy tagged `nostream`, because `ToolNode` passes them the config it captured before the wrappers ran. `before_model` and `after_model` stay as backstops, and the v3 stream transformer stays until v3 is removed. `create_agent` registers wrap hooks per class, so every `PIIMiddleware` registers them and input-only instances pass straight through. That gives a tool-less agent a `tools` node, skips the unknown-tool check, and adds wrapper spans; per-instance hook registration in `create_agent` would remove that cost. `strategy="block"` now raises inside the model or tool call, where retry middleware listed before `PIIMiddleware` would retry it, so the default retry predicate no longer retries a `PIIDetectionError`. A protected model streams no tokens and its reply arrives as one message, and protected tools no longer appear in the `tools` stream mode.
