Upgrade all packages

[dentiny]

Hi team, I'd like to keep project dependencies up-to-date, especially lancedb.

In this PR there're a few changes

• Upgrade backend dependencies, including LanceDB 0.36.0, PyArrow 25, Uvicorn 0.52.1, and python-multipart 0.0.32.
• Promote LanceDB 0.36.0 as the recommended Docker image and release-tag target.

Thanks for this. I ran it locally before merging rather than trusting CI alone, and it works well.

Numbers from a 20k row table with 128 dim vectors, median of 5 requests after a warm up:

• /rows?limit=1000: 0.230s to 0.191s
• /vector/preview?limit=1000: 0.096s to 0.054s

That is one machine and one table, so not a true benchmark. Nothing got slower, and the vector path got faster.
