"""CUDA attention kernel wrappers with torch fallback.

|
|
Public API:
|
|
- ``attn_decode`` — single-query decode attention
|
|
- ``attn_prefill`` — multi-query prefill attention
|
|
|
|
Each wrapper dispatches to its compiled CUDA kernel (``astrai.extension.attn_*``)
|
|
when available, otherwise falls back to ``torch.nn.functional.scaled_dot_product_attention``.
