fix(story-mode): a quoted report marks what it skips, a run that never loaded says so (review round 11)

From the fact-checker's last items:
- A helper's report quoted in a notice joined its first sentence to one
  from paragraphs later with nothing between: where text was left out,
  the balloon now says "…" (found in the report itself, so two
  sentences that follow each other are never marked).
- "The first run fails on purpose, as you asked" for a run that never
  loaded a test (a collection error) now reads "At first the tests don't
  even load, as you asked; the second run passes.", as a test panel
  already says it.
- A list intro without a count ("What failed and how I fixed it:") brings
  its items while they fit in 360 characters, not 260.
