Track colliding KOReader statistics rows independently and require verified explicit targets before upload. Keep unresolved history pending with a visible recovery path.
Fixes#1457
Recompute the open file digest and recover previously verified matches without guessing between duplicate files. Preserve stranded statistics across lifecycle retries and advertise plugin version 1.5.3 so installed devices can update.
Fixes#1497
Add two-way bookmark sync support between KOReader plugin and server. Include migration 0056 for bookmark sync columns, server endpoints and services for bookmark exchange, and KOReader plugin bookmark management with comprehensive unit and E2E tests.
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.
