It could be handy if charmcraft had an `fmt` command to apply a set of opinionated formatting choices. For example: - Sort metadata.yaml sections in a particular order, e.g. name - assumes - summary - description - ... - One line gap between each main section and no gaps anywhere else - actions.yaml and config.yaml entries sorted alphabetically - charmcraft.yaml: bases before parts; parts sorted by order of business. - etc.
