fix(story-mode): files written in Bash, the advisor, and honest checks, from review round 2

- Files a Bash call writes through here-documents (`cat > f <<'EOF'`, `tee`)
  are whole-file edits on the event: in the diff drawer, on the code page,
  in "N files changed". Before, a worker that wrote seven files that way
  drew a page with zero files changed. Labels leave the bodies out (the wire
  row was a wall of file text), and a relative target resolves against the
  transcript line's cwd unless the command changed directory first.
- A caption names the part of a one-liner that decided it (`node --test`,
  the commit), not its first line.
- The advisor (a server tool, answer encrypted in the transcript) is drawn:
  "Claude asks the advisor for a second opinion." It is not counted as a
  helper. Server web search maps to the web panel.
- Checks that all pass from the start read "Build and test, N rounds. Every
  check passes.", not as fixing.
- pytest's collection errors are counted apart: "The tests don't even load."
- A result remark replaces a step announcement on its check.
- A turn still open when the next prompt starts has ended; an interrupted
  turn is timed by its span.
- The mission drawer keeps prompts up to 4000 characters.
- Drawer: diff headers, titles and commands read relative to the session
  folder (the folder itself reads "."); a bare name under an `ls dir:`
  header links into that folder; the chosen answer is marked, not struck
  through; boards count errors.
- While a question waits, the pencils say "Waiting for your answer…";
  balloons start below the LIVE tag; the loop's balloon points at its
  verdict, above the board.
