/**
 * `/shelf/sync` returns three independent entry kinds:
 *   - `books[]`   — ebooks / imported / mp-style book entries
 *   - `albums[]`  — audiobooks / podcasts (官方 SKILL.md 强调专辑 = 有声书)
 *   - `mp`        — opaque "文章收藏" (article bookmarks) entry; non-empty
 *                   = 1 shelf entry but its content is NOT exposed here.
 *
 * Per official skill: shelf count = books.length + albums.length +
 *                     (mp non-empty ? 1 : 0). This adapter surfaces all three
 *                     row kinds in a `kind` column so callers can filter.
