Resolves NameError: name 'json' is not defined (#18).
The json module is used in _serialize_camera_data() and error handling
but was never imported when DA3 camera pose estimation was added in v1.3.4.
Bump version to 1.3.7.
- Fix scoping bug in __init__.py where module_version was undefined after
ImportError, causing incorrect DA3_AVAILABLE check
- Add defensive try/except guard around depth_anything_3 import in
depth_estimation_node.py to handle edge cases
- Move logger initialization before DA3 import to prevent NameError
- Bump version to 1.3.6
Resolves node loading failures on RunPod with PyTorch nightly builds
where the error node "Depth Estimation (Error)" was incorrectly shown
even when DA3 was intentionally not installed.
