是否应将 marker_gui 和 marker_server 的依赖关系作为可选附加组件展示出来?

The package publishes marker_gui and marker_server as command-line entry points (pyproject.toml:48-52). The GUI entry point directly launches Streamlit (run_streamlit_app.py:6-21). The server imports fastapi, and uvicorn (server.py:13-20, server.py:173-184).

However, streamlit, fastapi, uvicorn, and Python-multipart are currently listed only in the repository's dev dependency group (pyproject.toml:54-64). This group is not exposed as an installable package extra, so the README asks users to install the dependencies manually before using the published commands (GUI, server).

Proposed Fix Add feature-specific extras under [project.optional-dependencies] in pyproject.toml:

[project.optional-dependencies]
full = [
    # existing dependencies
]
gui = [
    "streamlit>=1.37.1",
    "streamlit-ace>=0.1.1",
]
server = [
    "fastapi>=0.115.4",
    "uvicorn>=0.32.0",
    "Python-multipart>=0.0.16",
]

Users could install them with pip install marker-pdf[gui] or pip install marker-pdf[server].
