MechaCat02 d6a109df2d feat(recommendations): content-based "Recommended for you" endpoint ...

Add GET /me/recommendations: rank mangas by weighted tag overlap with the
user's taste — explicit like +1.0, bookmark +0.5, dislike −1.0 (reaction
overrides bookmark). Per-tag affinities are summed, candidates scored by
their tags' affinity normalized by tag count (anti-tag-stuffing, à la
list_similar), with already-reacted/bookmarked/read mangas excluded and
net-negative candidates dropped (dislike down-ranks, not browse-hides).
Reuses manga_cols/cards_from_rows. Integration tests cover like-driven recs,
dislike down-rank, bookmark half-weight ordering, seen-exclusion, empty
cold-start, and auth.
