Complete LibTorrent4j 2.1.x API migration - Full refactor
- Migrated from deprecated SessionManager API to SessionParams - Replaced popAlerts() polling with AlertListener callbacks - Fixed Priority mapping (IGNORE, LOW, DEFAULT, TOP_PRIORITY) - Updated AddTorrentParams to use async_add_torrent via swig - Converted properties (.message, .best) from method calls - Fixed when/if expression exhaustiveness for Kotlin strictness - Added explicit Unit returns for control flow clarity BUILD SUCCESSFUL: TorrentEngine AAR compiles cleanly
