New package tensorrt_llm/executor/engine_client/: a typed, versioned, iteration-level request/response contract between the serving frontend and the engine (token deltas + explicit terminal frames over a strict msgpack codec), with an in-process client, exactly-once response routing, and frontend-side response assembly. When TorchLlmArgs.experimental_engine_client is enabled (or TLLM_EXPERIMENTAL_ENGINE_CLIENT=1), eligible OpenAI streaming requests run through this path and skip the per-request rank-0 GenerationResult; ineligible requests fall back to the existing path transparently. With the flag off there is no behavior change. Includes unit/replay/GPU test suites and design docs in the package. Signed-off-by: junq <22017000+QiJune@users.noreply.github.com>
