f56522d7 - fix: add missing return type annotations to type-checking utilities in generic.py (#44241)

fix: add missing return type annotations to type-checking utilities in generic.py (#44241) Adds missing `-> bool`, `-> int`, and `-> str | None` return type annotations to public utility functions in `utils/generic.py`, making them consistent with the newer `is_timm_config_dict` and `is_timm_local_checkpoint` functions already annotated in the same file. Zero behavior change — pure annotations only. Functions updated: - strtobool -> int - infer_framework_from_repr -> str | None - is_tensor -> bool - is_numpy_array -> bool - is_torch_tensor -> bool - is_torch_device -> bool - is_torch_dtype -> bool - is_mlx_array -> bool - is_flash_attention_requested -> bool
