Do we need to worry about a case where multiple compose files can be under one directory?

Since only the brave-compose.yml file will be searched for when a dir is passed we cannot handle multiple composefiles existing in the same dir given only the directory - there is no way of determining a composefile apart from the name and there can only be one file with that name in a dir.

However, we could extend the CLI command to accept multiple args and handle multiple composefiles that way. In the simplest case this would just a loop over input files running compose on each of them in turn, but we could also handle it in other ways such as merging the files into one.
