Add expo-bluesky-video-compress native module
Replaces react-native-compressor's video path with a local Expo module. Native pipeline: - iOS: AVAssetReader + AVMutableVideoComposition + AVAssetWriter with VideoToolbox encode, BGRA reader for HDR -> SDR conversion, BT.709 color tagging, DataRateLimits hard cap, AAC re-encode. - Android: MediaExtractor -> MediaCodec(decoder) -> GL pipeline -> MediaCodec(encoder) -> MediaMuxer. BITRATE_MODE_CBR for tight target enforcement, GL transform-matrix rotation (no double-rotation), raw AAC passthrough, hardware encoder selection with software fallback, QTI AVC denylist. Codec selection: 'auto' resolves to h264 (HLS pipeline + licensing). HEVC remains opt-in via codec: 'hevc' for future feature-flagged use. compress.ts adds probe-based smart-skip: clips that are already at or below 5 Mbps / 1920px / 100MB bypass re-encoding entirely. react-native-compressor stays as a dep for now since pickVideo and VideoTranscodeBackdrop still use its non-compression helpers; full removal is a follow-up.
