Weld webapp rewrite #9
Description
Streamlit has been a fantastic utility for quickly iterating on Weld, but at some point, we'll want to graduate to a proper frontend app.
With the help w/ our design team and a frontend person, we'll want to rewrite the webapp as a proper TS project that integrates with the UX repo. The streamlit app will likely exist for a long time afterwards since it's helpful for quick testing.
