- PiPController: add KVO on isPictureInPicturePossible, avoid duplicate setup, better logging - HLSRecorder: add stopRequested check after Task.sleep to ensure recording exits cleanly - HLSRecorder: add 120s timeout to remuxToMP4 via TaskGroup to prevent hanging - HLSRecorder: improve presentActivitySheet VC lookup (key window, foregroundActive scene) - Add detailed logging throughout recording/export flow for debugging
