Add Android foreground service support for downloads to prevent OS process killing during long operations. Fix multiple error handling issues: foreground service leak on exceptions, polling stuck forever on failure, double-counting chapters on retry, silent retry failures without user feedback, and app crash if background service init fails. Replace inaccurate failed chapter count heuristic with actual data. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
