fix(story-mode): plans you approved, project rules, tag lookups and dry runs (review round 12)

From a reader who has never written code:
- "a save your prompt here did not ask for" on a save that was step 3 of
  the plan you approved ("Verify and commit"): a commit step in an
  approved plan asks for the save. When Claude says a project rule asks
  for its commits (read on its whole message), the line says "…; your
  project's rules do".
- "a check after that fails" read as a failed test where it was `git
  describe` finding no tags: "the version-tag lookup after that fails
  (there are no tags yet)".
- The dry run you asked for never showed: the terminal card took the
  last command's edge-case errors. A dry run in the panel is now what the
  card shows, its "a -> b" lines, under "Claude does the dry run you
  asked for: it shows what would happen, changing nothing."
