/api/v1/post/history/diff
Returns a structured diff between two revisions of the same post and locale.
Title is word-grain (titles are short, word grain reads naturally), content is line-grain (HTML/markdown bodies — line grain keeps block edits readable). Each diff segment is tagged add / remove / context; concatenating context+add produces the to document, concatenating context+remove produces the from document.
Both revisions must belong to the same post and same locale; cross-post or cross-locale diffs return an error envelope.
