Summary

• Enable Denglin QY CUDA runtime device backend (Device::Type::kQy, runtime/graph APIs).
• Define kEventNotReady for QY so test_qy_runtime compiles (parity with other CUDA backends).

Motivation / related

• Required by Ops #1038 / LM #618 QY stack.
• Supersedes working tip of feat(qy): enable QY CUDA runtime device backend #49 (left open).

Type of change

• feat
• fix (kEventNotReady)

Platforms affected

• QY

Validation

• Host Denglin QY, DENGLIN_DEVICES=3.
• Configure/build with WITH_QY=ON + testing; ctest → 13/13 PASS (incl. test_qy_runtime / test_qy_graph).
• See PR smoke comments. Log: nov_milestone/logs/prhead-verify-20261113/rt-ctest.log

Checklist

• format/build/ruff green; head includes kEventNotReady fix
• Conventional Commits title/branch
