fix(tcfeed): stop telling --refresh it changed nothing (#136)

The footer is gated on !fix and does not know --refresh exists, so a run
that had just pushed a commit to forty-four repositories signed off with

  Nothing was changed.

That is not a cosmetic wording problem. --refresh is the one path that
writes to other people's forks without being asked to again, and the line
an operator reads at the end of it is the line they will believe. Saying
nothing happened after forty-four commits invites re-running it to make
something happen.

Gated on !fix && !refresh. The read-only pass still prints it, which is
where it was always true and is the only place it belongs.

Verified both directions: --refresh on an already-current repository
prints its result and stops, and a plain check still prints the footer.
