Save ONE episode's outline.

Replaces one season-map episode's outline with outline and leaves every other episode as stored — the same writer as the episode's Outline tab and Slug's save_episode_outline, so it is the outline outline coverage scores and the season planner hands the writer. Read the outline map first to carry over what should stay. A structure that is not three acts (six acts and a tag, a scene list) goes in titleNotes whole. An episodeId the season map does not plan is a 400. Free. Scope: story:write. A product project is refused with 409 project_not_story (details.work: outline): its Bible lists features, not episodes.
