Wing Lian	ff5d6393c8	replace legacy attention boolean flags with capability properties ... Replace checks with capability-based properties derived from attn_implementation This separates three concerns that were conflated under flash_attention: 1. Backend selection -> attn_implementation enum 2. Packing capability -> attn_supports_packing property 3. Flash-attn library dependency -> attn_uses_flash_lib property	2026-04-23 22:27:01 +00:00
Wing Lian	aee8c75d64	refactor attention handling	2026-04-23 22:27:01 +00:00
