uv 0.8.0 introduced a [breaking change](astral-sh/uv#14447) that affects how `uv run --with` invocations work. The new version creates an additional ephemeral environment layer on top of the cached environment, which breaks our ability to access layered Jupyter static assets from the virtual environments that uv creates. juv relies on uv's previous behavior where the layered virtual environments were directly accessible, allowing us to combine Jupyter static assets from multiple environment layers. The new ephemeral environment prevents this access pattern. We'll need to find an alternative approach for accessing layered Jupyter static assets before removing this upper bound.
