Fixed(cli):

- `ls` and `mirror` commands now provide informative feedback when no documents are found or filters skip all files, resolving the issue where they would exit silently (#860).
- The command-line argument `vault` has been renamed to a more appropriate name, `databaseDir`.
- The `mirror` command now accepts a `vault` directory, which specifies the location where the actual files are stored. For compatibility reasons, the previous behaviour is still supported.
