Add `--no-install-local` to `uv sync`

[danielgafni]

Summary

This flag would be similar to --no-install-workspace, but it would also affect local non-workspace dependencies.

This is desired in optimized docker builds where we don't want to install frequently changing local packages before installing heavy third party dependencies.

Currently this workflow is well supported when depending on other packages from the same workspace, but these packages may also come from other workspaces.

Example

Current command:

uv sync --no-install-workspace \
        --no-install-package anam-face-extraction \
        --no-install-package anam-syncnet \
        --no-install-package anam-data-utils \
        --no-install-package anam-dagster \
        --no-install-package anam-training-data \
        ...

Desired command:

uv sync --no-install-local

I think this makes sense, IIRC we considered this in-scope at the time but just punted it on it due to lack of demand?

[zanieb]

Yes we wanted to see if there was a strong justification for it, given that you can just enumerate the packages.

[danielgafni]

It definitely feels like it should be there.
I don't want to be maintaining these lists in dozens of Dockerfiles across all the projects I have in different workspaces.
