Description
### Custom Node Testing
- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)
### Expected Behavior
Either cross-compatibility, or error message indicating LoRA is incompatible with model architecture, operation aborts cleanly.
### Actual Behavior
ComfyUI logs ~1500 "lora key not loaded" warnings followed by ~228 shape mismatch errors, then continues execution anyway:
lora key not loaded: lora_unet_double_blocks_0_img_mod_lin.lora_up.weight
[...~1500 similar warnings...]
ERROR lora diffusion_model.single_blocks.X.linear2.weight shape '[6144, 24576]' is invalid for input of size 47185920
[...~228 similar errors, each layer 3x...]
Execution continues despite ~1700 logged problems. Corrupted tensor state gets pushed to GPU, causing OOM on 96GB card and system instability requiring reboot.
### Steps to Reproduce
Load Flux 2 Dev model
Apply a Flux 1 LoRA (architecturally incompatible - different tensor dimensions in single_blocks)
Attempt to run generation
Observe error spam followed by OOM and potential system instability

Search for `cudaErrorMemoryAllocation' in https://docs.nvidia.com/cuda/cuda-runtime-api/group__CUDART__TYPES.html for more information.
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1
Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions.

Environment: ComfyUI 0.9.1, PyTorch 2.9.1+cu130, CUDA 13.0, NVIDIA RTX PRO 6000 (96GB), Windows 11
~1700 total warnings/errors logged before crash. Suggest failing after first incompatibility detection rather than exhaustively logging every mismatch.
