The workspace npm ci printed nothing until 'added N packages': builders
set CI=1, which turns npm's progress off, and the stage name only went
to the desktop UI's status file.
Print a line before npm ci, and pass --progress=true so a terminal gets
npm's spinner back (npm still shows it only on a TTY, so piped output
such as the desktop app's log stays clean). The flag stays out of the
receipt-keyed args, so existing installs are still reused.
