subscription remove/update, collection add/remove, entry mark-read/unread,
feed refresh and list update/delete/remove-feed printed response.data,
which those responses never carry, so they printed no data at all. They
now print the fields the API sends, { lastSyncId } or {}.

The export endpoint answers with raw XML, not the JSON the SDK types, so
`folo opml export` printed an empty object and `--output` failed with an
undefined data error. The CLI now reads the response as text, prints or
saves it, and names it folo.opml when --output is a directory.
