Two efforts to convert a Python program to a Texera workflow

[chenlica]

Currently there are two efforts to convert a Python program to a Texera workflow:

1. Using an LLM to do the conversion. It can leverage latest AI techniques, but doesn't guarantee the equivalence between the two "programs". It's led by @zyratlo and @mengw15. See the discussion [WIP] Python Notebook → Texera Workflow migration tool using LLMs #5959 .

2. Using compiling techniques to do the conversion. It can guarantee the equivalence between the two "programs." It's led by @carloea2. See this discussion Proposal: Statement-level Python-to-Texera workflow compiler MVP #8160.

These two approaches have their pros and cons. We can present both to users and let users decide.

I want to start this discussion to let the community be aware of the two efforts, and provide feedback, if any.
