In preparation for [other-derivation-schemes](other-derivation-schemes.md), move the current `vault`-specific command-line interface into a subcommand `vault`, and a matching configuration file `vault.json` instead of `config.json`.

Include machinery to automatically migrate to `vault.json`, with fallback to `config.json` if the former is not writable. (v1.0 will no longer support `config.json` or auto-migration.)
