4grayandClaude Opus 4.7 29fe8b905c perf(database): partial covering index for visible categories
Three queries filter on categories.hidden = false:

- getGlobalRecentlyAdded — every dashboard load (now sorts by added DESC
  on the indexed content side after the prior CAST removal)
- searchContent — Xtream search with excludeHidden
- globalSearch — global Xtream search with excludeHidden

All three start from content and join into categories on the
category_id PK. The hidden filter is then applied per-row, requiring a
row lookup for every result candidate — even before LIMIT.

Add a partial covering index on categories: idx_categories_visible(id,
playlist_id, type) WHERE hidden = 0. Two wins:

- Covering: SQLite serves the join (id) plus filters (playlist_id,
  type) and the hidden = 0 predicate directly from the index without
  ever touching the categories row.
- Partial: hidden categories are absent from the index, so they're
  pruned before any work happens — no row lookup, no comparison.

Schema mirrored in Drizzle so the ORM stays the single source of
truth. CREATE INDEX IF NOT EXISTS so existing DBs pick it up on next
startup with no migration needed.
