The `filterExclude` event doesn't include `type`

[citizenmatt]

When calling lore --json status --scan, any ignored files and folders are reported with the filterExclude event. The event reports the exclusion reason and the path, but the client doesn't know if the path is a file or directory. The repositoryStatusFile event, also emitted during lore --json status --scan includes a type property which is either "file" or "directory".

If filterExclude also reported type, the client could correctly display UI for an excluded file or folder without another call to disk.
