`GET /library/session/{cid}/version/{ver}`

## Request

One version's content + what changed since its parent — the "open the commit" view. Returns the
full transcript at `ver` (for a full read) plus, when this version simply APPENDED to its parent
(the common backup case), the appended text so the UI can render only the new turns. A wholesale
rewrite (e.g. a squash) is flagged `rewritten` with coarse ±line counts instead. Account-scoped.
