Add a private per-user reaction resource: a manga_reactions table (one row per user+manga, like/dislike, cascades) and endpoints PUT/DELETE /mangas/:id/reaction plus GET /me/reactions/:manga_id, wired on the existing per-user seam (mirrors bookmarks/read_progress). Unknown manga → 404 via the FK-violation mapping; an invalid reaction value → 422. Reactions are never exposed publicly — this is a taste signal for the upcoming content-based recommendations. Integration tests cover set/toggle/clear/read, per-user isolation, and the 404/422/401 paths. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

//! Manga reactions (like/dislike) — a private, per-user taste signal.

//! Writes require auth; the read is scoped under `/me/` so the URL can't be

//! used to peek at another user's reactions.
