Trim the fit confirmation to a terse "Fits!"

Echoing the word back plus its letter count ("Heart. 5 letters — it
fits!") slowed every exchange for no information: the user just said the
word. A fitting answer is now confirmed with just "Fits!" and the session
moves on. The one exception stays: a homophone/digit rescue still spells
the accepted word first ("A, T, E — fits!") because there the entered
spelling differs from what was voiced (REQ-ANS-006).
