Subject: [PATCH] fix: make lazyllm an optional dependency (fixes #373)

lazyllm is only used when client_backend is set to lazyllm_backend,
not in the default configuration. Requiring it unconditionally caused
pip install memu-py to fail because lazyllm>=0.7.3 is not available
on PyPI.

Move lazyllm to optional-dependencies under the [lazyllm] extra so
users who need the LazyLLM backend can install it with:
  pip install memu-py[lazyllm]
