Subject: feat(assistant): the Do row of file operations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Conversions, extraction, merge and compression on the staged files from
the file state, one at a time, with Stop; Compress… opens its formats.
To .md goes through the daemon's write, the rest through fileops. The
card keeps the result line, Saved name with Open and Folder, or the
error, so another operation can follow on the same files. Results land in
Documents/Assistant.
