Remove `virtual` from `uv.lock` to reduce the lockfile size for large workspaces. In a large workspace, `package.metadata` begins dominating the lockfile size. Specifically, `virtual` just repeats the workspace member path that we already know from the workspace member list, so we can omit it and save a good chunk of size. Notably, this is not backwards compatible: Older uv versions expect the `virtual` field, so activating the preview feature only work when using uv with that preview feature. (We could add it as a setting, but then older uv versions don't see that setting either.)
