- useApplySpeedCurve hook with MediaBunny encoding pipeline (no frame blending, no preview mode)
- Standalone applySpeedCurveAsync export for store/API usage
- SpeedCurveProgress type for progress tracking
- EaseCurveNodeData interface with bezierHandles, easingPreset, outputDuration, status fields
- "easeCurve" added to NodeType union and WorkflowNodeData
- Default dimensions (340x480) and node data (easeInOutSine preset) registered
- Shared applySpeedCurveCore extracts common logic between hook and standalone function

After all video frames are processed (phase 1), the final video duration
is known from highestWrittenTimestamp. Audio is now trimmed to that
exact duration before being encoded into the MP4 (phase 2). Prevents
audio tracks from extending beyond the video.

When videoDuration is 0 (unknown at call time), prepareAudioAsync was
computing targetDuration as max(0.1, 0) = 0.1 seconds, truncating the
audio to 100ms. Now computes the actual decoded audio duration from
buffers and uses that when videoDuration <= 0.

Use MediaBunny as the primary decoder following the documented pattern:
getPrimaryAudioTrack() + canDecode() check + AudioBufferSink.buffers().
Falls back to Web Audio API's decodeAudioData if MediaBunny cannot parse
the format (e.g. unusual codecs). This ensures MediaBunny handles
container formats it supports while Web Audio API catches the rest.

MediaBunny's Input/BlobSource is designed for video containers and cannot
parse standalone audio files (MP3, WAV, etc.), causing "unsupported format"
errors at getAudioTracks(). Replace with Web Audio API's decodeAudioData
which natively handles all browser-supported audio formats.

- Port useAudioVisualization.ts with waveform peak extraction
- Port useAudioMixing.ts with prepareAudioAsync standalone function
- Port useStitchVideos.ts with stitchVideosAsync and checkEncoderSupport
- Export applyFades from useAudioMixing for shared use
- Remove preview mode logic from useStitchVideos (always full quality)
- Inline constants (DEFAULT_BITRATE, MAX_OUTPUT_FPS) in useStitchVideos
- All hooks use MediaBunny for audio/video processing
