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.
