rust-analyzer status should be easier to see on the bottom bar, with a color

[Evalir]

Sometimes when you're editing your rust project's deps, it's easy to break the crate and cause rust analyzer to be unable to run since the Cargo.toml isn't valid. In vscode's case, this is highlighted with a red symbol on the bottom left, which if you click it, let's you know that the Cargo.toml is broken and why. In Zed, the equivalent is only a popup which is easy to close, which if you do, there's no other visual indicator telling something's broken at all.
