feat: Add restore cutout depth extension with edge depth correction

- Introduced a new extension for restoring cutout depth with edge correction.
- Implemented edge depth extension algorithm in `edge_depth.py` to enhance depth accuracy near cutout edges.
- Updated `generate_moge_artifacts` to include an option for extending depth edges during depth generation.
- Modified cutout job processing to enable edge depth extension based on depth request.
- Added comprehensive tests for edge depth functionality, ensuring correct behavior under various scenarios.
- Updated existing node loading functions to remove asset revision dependencies, simplifying the loading process.
- Created new design and proposal documentation outlining the goals and decisions for the extension.
