"""CUDA attention kernel wrappers with torch fallback.
Public API:
- ``attn_decode`` — single-query decode attention
- ``attn_prefill`` — multi-query prefill attention
- ``attn_paged_decode`` — paged decode attention (direct page-table access)
Each wrapper dispatches to its compiled CUDA kernel (``astrai.extension.attn_*``)
when available, otherwise falls back to ``torch.nn.functional.scaled_dot_product_attention``.
