    Generate constraints from uv.lock instead of skipping constraints download 
(#63675)
    
    When installing from sources, the constraints file was not being
    generated, which meant downstream steps had no constraints.txt to
    reference. Now we use `uv export` to generate constraints from the
    lock file, consistent with the pattern already used in entrypoint_ci.sh.
