feat: M-IOS-INFO Batch D-F complete (38/38)

Batch D: MarkedAsRead UI, reading progress query, position restore, continue learning, source reading status
Batch E: NetworkMonitor, summary/trend/heatmap alignment, learning records, error handling, background upload, debug/logging
Batch F: Test stubs, iOS integration doc
Batch G: V2 FFI/MarkedAsRead/export-ack coverage verification
