Pull request overview
This PR aims to improve compatibility between GGUF quantization paths and torch.compile, and adds a CUDA test intended to cover the GGUF + compile workflow.
Changes:
- Add a new CUDA quantization test file targeting GGUF Q2_K_S with
enable_torch_compile=True. - Adjust GGUF-related quantization math to use floating-point bases in exponentiation/pow operations (to better support compilation).
- Downgrade the “algorithm extension” log from
warning_oncetoinfo.

| auto_round/compressors/base.py | Changes the log level/behavior when algorithm extension is enabled. |
| auto_round/alg_ext.py | Tweaks GGUF-related quantization computations (float exponent base / torch.pow) and adds a commented Dynamo-disable hint. |
