-The upgrade skips releases published within the last 7 days, so a broken or
-compromised release has time to be yanked before it can land in the lock file.
-Change the cutoff with `exclude_newer`, which takes anything uv's

-`30 days`, or `false` to upgrade to the newest releases with no cutoff at all.
-It reaches uv as `UV_EXCLUDE_NEWER`, so it overrides an `exclude-newer` the
