fix(story-mode): a stop names the step Claude was on and what its to-do list still had open

From review round 9: "You stop Claude here, during its step 3." said
where Claude was, not what that meant. The stop now carries the step's
own words, "during its step 3 (new tests under test/)", and when Claude
kept a to-do list, what was still open on it: "Not done yet: Write the
new tests; Update the README and 1 more."
