🎯 What: The testing gap addressed The open_safetensors function in Native/pcai_core/pcai_media/src/hub.rs lacked adequate testing for actual file loading scenarios.

📊 Coverage: What scenarios are now tested

• Valid single .safetensors files containing dummy tensors.
• Valid multiple sharded .safetensors files spanning multiple parts containing dummy tensors.
• Invalid or corrupted .safetensors files which ensure error propagation.

✨ Result: The improvement in test coverage open_safetensors is now comprehensively covered against happy paths (successful parsing) and common edge cases.
