Wave Loop 366 — IGLA CODER+RACE + retry board flash + one safe gen-verilog sub-fix

[gHashTag]

Wave Loop 366 targets:

• 42-variable accumulation probe
• 41-variable minus accumulation lattice
• Novemdecuple cancellation (depth-19 residual mac(x,a,.plus))
• Zero-weight nonuple closure
• Retry flash of generated ternary MAC bitstream to QMTech Wukong V1 via dlc10
• Land one safe gen-verilog sub-fix from the remaining lowering defects, or document the attempt in a focused follow-up issue if no fix is regression-free
• Produce W366 report and W367 cooperation variants

Closes #1252
