v1.4

What's Changed

Bug Fixes

• Remove resizeEvent override from VideoProxy (fought layout)
• predicateAction lookup uses key() instead of values().contains()
• turnOn() was unsubscribing instead of subscribing WindowAboutToBeBuilded
• ffprobe stdout read before deleteLater() (read-after-free)
• play() early-returns if videos still empty after refreshSource()
• checkResource() debounced to suppress notification spam
• CMakeLists now calls find_package(PkgConfig) before pkg_check_modules
• %0 → %1 in notification string
• Volume migration now persisted to DConfig on first run
• checkResource lambda guarded against stale this after turnOff()
• disableAction no longer wipes pauseOnFullscreen/pauseIdleSeconds

New Features

• Volume control (0–100) replacing binary enableAudio toggle
• Playback speed control (0.25×–2×) persisted in DConfig
• Per-screen video assignment for multi-monitor setups
• applyMpvSettings() applies volume + speed on every play/refresh
• Idle/scale/speed/volume menus use QActionGroup (exclusive)
