fp64_emulation_probe — DRIVE `ozaki` op

• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.fp64_emulation_probe() (to call the implementation directly, import ozakimm; ozakimm.fp64_emulation_probe(); from the registry, opsdrive.get("fp64_emulation_probe"))

cuBLAS の FP64 エミュレーション(CUDA 13.0 Update 2 以降)が、この計算機で使えるかを表で返す。

例外を出さない: GPU・CUDA・cuBLAS 13 が無ければ `available=False` と理由を返す(重い依存は持たない。ctypes で

ライブラリを開いて版を読むだけ)。返り: `available(bool)、rows(候補ごとの library・path・loaded`・

`cublas_version・emulation_api(cublasSetEmulationStrategy があるか)・gpu`(ハンドルを作れたか)・

`reason)、how(有効にする方法)、note`。

有効にする方法は opt-in: math mode `CUBLAS_FP64_EMULATED_FIXEDPOINT_MATH`、またはコードを変えずに

`CUBLAS_EMULATE_DOUBLE_PRECISION=1`。cuBLAS の文書はエミュレーション中はビット単位の再現の保証が外れると書く

—— 再現が要るなら :func:matmul_reproducible。
