Publish llm-d-planner to PyPI

[anfredette]

Context

The python-wheel branch adds wheel packaging support — the Planner class can be used as a library with pip install llm-d-planner. However, the package is not yet published to PyPI, so users must install from a local build or from GitHub.

What's needed

1. PyPI account — register llm-d-planner package name on pypi.org
2. API token — create a PyPI API token for the project
3. GitHub Actions workflow — add a release workflow that builds and publishes the wheel on tag push (e.g., v0.1.0)
4. First publish — uv build && twine upload dist/* (or via the workflow)

After publishing

pip install llm-d-planner              # core library
pip install llm-d-planner[server]      # with REST API
pip install llm-d-planner[llm]         # with Ollama for intent extraction
