fix(story-mode): what the captions blurred for a reader who skims (review round 11)

From an engineering manager skimming titles and captions:
- "but a check after that fails" under "Mission complete!" where the
  prompt said that step may fail now adds ", as you said it might".
- Saves no prompt of the turn asked for (a project rule, or Claude's own
  idea) were indistinguishable from requested ones: the turn's first such
  save carries a small line, "a save your prompt here did not ask for".
  "save its log with tee" no longer counts as asking to save the work.
- The first save on a branch Claude created says which: "saves the work
  on a new branch (feat/csvstat)".
- "Claude changes 3 files" hid an edit to your CLAUDE.md: a panel that
  wrote some files and patched others says both ("Claude writes
  README.md and .gitignore and changes CLAUDE.md."); a file created and
  then edited in the same panel is written.
- A turn with a problem left and work still out read "Done for now";
  the catch now wins the title.
- A helper's report that is only a path reads "reports back with the
  file it wrote: README.md."
