Fix #34: ASW_Basic 兜底恒出方案; 搬移效率下限不满足降级为 warning (不判违规)

Browse Source 
- constraints.py: ASW_Basic/ASW_Basic_降核 的 dValue 效率下限不再计违规
  (DMA 仍能工作只是效率低; 真正不可行的只有容量/核数硬约束);
  IterBatch/MergeBatch/StreamK 等有替代分支的分支仍按违规处理 (不满足条件不该进)
- asw_basic 枚举尾部: 严格 256B 偏好无解 -> 放开约束4 按 128B 硬下限给最优可行 tile,
  note 标注"效率降级"; 128B 硬下限也不满足的极端形状 (如 N=8 int8, B 侧 dValue=8B
  物理不可满足) 仍给 Base tile 方案 + 标注效率降级 (搬移效率崩塌)
- evaluator advice / router 仲裁文案含"效率降级"提示 (plan.note 同步)
- docs/06 Step1 增加"兜底分支恒出方案"段落 (效率降级 vs 违规的语义分层)
- 回归: b32_m16_n8192_k7168 分解 = Base 16x1024 + tile 16x1024 + k_l1=112
  (L1 双缓冲 ⌊L1/(2·(16+1024)·2)⌋16=112 反推) 入测试; 极端形状 feasible=True +
