This adds a new annotation to commands that are known to be frequently used, and allows setting a custom weight/order for these commands to influence in what order they appear in the --help output. I'm not entirely happy with the implementation (we could at least use some helpers for this, and/or make it more generic to group commands in output), but it could be a start. For now, limiting this to only be used for the top-level --help, but we can expand this to subcommands as well if we think it makes sense to highlight "common" / "commonly used" commands.
