Thank you a lot for the UV feature, it will be very beneficial.
I left just a small comment :)

It might be beneficial to add Floogen as a workspace to enable development on Floogen while testing on Picobello.

I tried, the problem is that uv_build does not like symlinks at all. However, the following works and is also recommended for local development:

bender clone floo_noc

Then in pyproject.toml

[tool.uv.workspace]
members = [
    "working_dir/floo_noc",
]

[tool.uv.sources]
floogen = { workspace = true, editable = true }

I also added a comment in pyproject.toml
