fix: template prompt bloat and variable substitution failures

- chapter_polish: remove sections:deliverables — chapter text already in
  {chapter_text}; this caused 150KB+ prompts for late chapters (40MB logs)
- chapter_roundtable: require structured CONSENSUS REACHED block so
  key_changes is always formatted as an extractable string; change
  key_changes schema from list to string to match
- book_chapter: remove sections:history to reduce context; restructure
  Pass 0 to plan-only (no prose output) so the chapter is only written
  once in Pass 1 instead of twice; add explicit instruction in package
  hint to copy full chapter_text into spawn context
- short_story: remove sections:history and sections:deliverables (standalone
  task, needs neither); restructure Pass 0 to plan-only, Pass 1 to write;
  add note to handle literal {genre_name} placeholders gracefully
- recipe_develop, ai_article_write, blog_write: remove sections:history
  (these standalone tasks do not need full project conversation history;
  deliverables kept so they can read the research/plan file)
