If I want to know which packages versions will change when I do a upgradable relock, I might want to do the following command

$ uv lock -U --dry-run

Currently, there seems to be no direct instruction to achieve a similar effect. The following command will report an error and cannot achieve the effect I want.

$ uv lock -U --locked
Resolved 10 packages in 126ms
error: The lockfile at `uv.lock` needs to be updated, but `--locked` was provided. To update the lockfile, run `uv lock`.

This makes sense to me.

Makes sense. There's also uv lock -U && git diff && git reset --hard, but we can do better.

Add support for --dry-run mode in uv lock (#7783)
98523e2 
This PR adds support for `uv lock --dry-run`, as described in issue
#6408.

One thing to note: this functionality, as implemented, isn't limited to
`-U` (if someone adds a dependency to the project's `pyproject.toml`,
the plan will include these changes).
