feat: add additional binary file types to scan exclusions

Add several new file types to be excluded from scanning operations:
- Debug files (pdb, dSYM)
- ML/Data model formats (h5, pb, onnx, pt, safetensors, etc)
- 3D model formats (glb, gltf)
- Editor swap/temp files (swp, swo)

These exclusions will improve performance and relevance when scanning
repositories by ignoring common binary and temporary files.
