Lifecycle handlers previously blocked on network work, so closing or suspending a book stalled the device on slow or offline links. Persist snapshots first and drain them through a lifecycle outbox with connected-state gates and phase-aware retries, so the UI stays responsive and pending work survives restarts. Move persistence behind a state manager with atomic flushes, and chunk sweeps, bulk downloads, and annotation exchange through a background queue with checkpoints and transfer policies, so large libraries make progress incrementally instead of restarting from scratch after an interruption. Server side, add bulk manifest and page stats endpoints with batched queries and catalog query filtering so the plugin can reconcile many books per round trip rather than one request per book.

`respond(sql, params)` answers one query and returns a column-major result set

(see resultSet) or nil for "no rows". `opts.fail_opens` makes that many opens

fail, and `opts.fail_queries` that many queries error, so reopen-and-retry can

be exercised.
