Add Blender runtime validation

[Ahmed-Hindy]

Summary

• add Blender runtime discovery and validation helpers under materials_processor.dcc.blender.runtime
• add a headless validation script with an optional material traversal/recreation smoke test
• add unit coverage plus a pytest -m blender integration marker
• normalize Blender socket array values during traversal so real Blender data serializes cleanly

Validation

• uv --native-tls run pytest tests/test_blender_runtime.py tests/test_blender_support.py tests/test_public_imports.py
• uv --native-tls run pytest -m blender
• uv --native-tls run python scripts/validate_blender_runtime.py --smoke-material --timeout 120
• uv --native-tls run pytest
• uv --native-tls run ruff check src tests scripts
• uv --native-tls build

Notes

Validated locally against Blender 4.5.0 at C:\Program Files\Blender Foundation\Blender 4.5\blender.exe with embedded Python 3.11.11.
