- Use a single EfficientSAM ONNX model for ObjectMask seed mask generation
- Add EfficientSAM prompt preprocessing and mask candidate selection
- Keep seed-frame output as the raw EfficientSAM mask while still seeding XMem
- Add ClipProcessingJobs::PreviewObjectMask for single-frame interactive previews
- Accept EfficientSAM model JSON keys while preserving legacy encoder_model aliases
- Remove ObjectMask protobuf shutdown call that could destabilize Python teardown
- Add ObjectMask ONNX validation coverage
- Add ObjectMask effect for rendering and exposing generated object masks
- Add EdgeSAM preprocessing path for prompt-based seed and reseed masks
- Add XMem ONNX propagation between seed frames for single-object tracking
- Support positive/negative points, positive rect prompts, and prompt keyframes
- Store generated masks in protobuf data for playback and downstream effects
- Add mask color/alpha plus stroke color/alpha/width effect controls
- Register ObjectMask with effect discovery and clip preprocessing jobs
- Add focused ObjectMask effect tests
