- Fix absolute head index computation in fwd/bwd triton kernels
- Add k_dim_ceil (power-of-2 alignment) for triton compatibility
- Handle v_dim=0 case in both forward and backward kernels
- Use proper mask_k/mask_v instead of single mask
Fix absolute head index computation in fwd/bwd triton kernels for MLA YaRN RoPE. Add k_dim_ceil (power-of-2) for proper triton alignment and handle v_dim=0 case gracefully. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
