Module validation 

Model validation and integrity checks for embedding models

This module provides comprehensive validation capabilities including:

• Checksum validation (SHA-256, BLAKE3) for model integrity
• Dimension consistency checks across model layers
• Model signature and format verification
• Model metadata validation

All operations use proper error handling with no unwrap() calls.
