feat: DV Profile 7→8.1 RPU conversion via libdovi
Convert Dolby Vision Profile 7 RPU NALUs to Profile 8.1 using libdovi
native bridge, preserving dynamic tone mapping on devices with DV8
decoders. Falls back to HEVC stripping when no DV8 decoder is present.
- Add JNI bridge (dovi_bridge.cpp) wrapping libdovi's RPU converter
- Download prebuilt libdovi from edde746/libdovi-builds releases
- DoviConvertingTrackOutput: DV81 mode converts RPUs, HEVC_STRIP strips
- Retry logic: if native DV7 decoding fails, auto-retry with conversion
- Performance overlay shows active DV conversion mode
