update: download & lock project dependencies

melody update

Install the latest versions of packages specified in Melody.toml. You will use this command when initializing a new project to fetch all the necessary metadata about the dependency tree, and install them into your project’s vendor subdirectory. Once this command succeeds, you will be able to run all standard go commands without modifying your environment.

melody update <package1> <package2> ...

Once you have your dependencies locked in Melody.lock by the bare update, you can use this form to update one or more specific dependencies while trying to minimize changes to the rest of the locked dependency graph.
