fix(story-mode): a push in its own command is not a commit

From review round 6: commit, then push as a second command (the most
common way to ship) drew as "Claude saves the work in 2 commits and
uploads it." for one commit, and the commit's message was dropped. A
command's `commits` was only recorded above one, and the save panel then
counted every save command as one. It is now recorded whenever a command
commits and is the only thing counted: "Claude saves the work and uploads
it: "feat: add mode()"." A push of earlier commits reads "Claude uploads
the work."
