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."

In plan mode the plan file under `~/.claude/plans/` is planning (intent `plan`, its numbered steps as `todos`), and `ExitPlanMode`'s result carries the plan (`output`) and your answer (`Approved` / `Sent back`).

 - `panels`: at most 12, each `{ kind, events, caption: { story, director }, balloon?, files?, notes?, helpers?, todos?, tests?, ok?, rounds?, roundsOk?, question?, live? }`, with `events` as indices into `events`. A run panel's `printed` holds the first lines its last command printed (its last lines when it failed), for the terminal card: the card is drawn on the canvas and goes into a saved image, so lines that look like secrets are left out and addresses and long token-like strings are masked. `balloon.who` is `you`, `claude` or `note` (words that start a turn but are not yours: a background job's report, another session's message); a helper's report keeps its own words there (`"<helper>" reports: …`, its first sentence and key points, absolute paths shortened to their last two parts). A loop's `roundsOk` lists every test run in order, `true` where it passed and `null` for one still running, so a failure inside a round that passed in the end still shows, and a live loop shows the runs that finished. Kinds: `mission`, `investigate`, `research`, `plan`, `backup`, `fix`, `check`, `loop` (fix and check rounds folded), `run`, `save`, `ask`, `compact`, `montage` (quieter panels folded to fit) and `complete`.
 - `filesChanged`, `added`, `removed` (summed per edit), `helpers` (the turn's own helper calls; a report turn's prompt carries the helper it answers, which is not counted), `helpersRunning`, `noneWorked` (every tool call of the turn failed, so the last panel is no celebration; a command whose last check only found nothing, exit code 1 after its answer, does not count as failed), `durationMs`, `partial` (the turn began before the part that was read) and `truncated` (older outputs, hunks and helper texts were dropped to keep the page small: a page carries at most 120,000 characters of them, newest first; an edit that lost its lines keeps its counts and an empty `hunks`).
