Prevent the device from dropping to 10MHz CPU during first-time chapter indexing, cover prerendering, and other CPU-intensive reader operations. Three issues addressed: - ActivityWithSubactivity now delegates preventAutoSleep() and skipLoopDelay() to the active subactivity, so EpubReaderActivity's signal is visible through the ReaderActivity wrapper - Added post-loop() re-check of preventAutoSleep() in main.cpp to catch activity transitions that happen mid-loop - EpubReaderActivity uses both !section and a loadingSection flag to cover the full duration from activity entry through section file creation; TxtReaderActivity uses !initialized similarly Also syncs HalPowerManager.cpp log messages with upstream PR #852.
