model op• Data kinds: metrologymodel → scalar
• Call: import fullseye as fs; fs.ledger.add_metrology_object_circle_measure(model, row, col, radius, n: 'int' = 40) -> 'int' (to call the implementation directly, import metrology; metrology.add_metrology_object_circle_measure(model, row, col, radius, n: 'int' = 40) -> 'int'; from the registry, opsmeasure1d.get("add_metrology_object_circle_measure"))

円計測オブジェクトを追加(add_metrology_object_circle_measure)。
参照円(中心 `(row, col)、半径 radius [px])を model["objects"]` に積む
(dict をその場で更新)。`apply_metrology_model は円周を n` 等分した角度に
点を置き、各点で 半径方向(外向き法線)に測定線を張ってサブピクセルの
エッジを取り、最小二乗の円フィットで中心と半径を出し直す。
• `radius: 参照半径 [px]。実物とのずれは apply の measure_length`
(既定 ±6 px)以内に収まっている必要がある ―― それより外のエッジは見つからない。
• `n`: 円周のサンプル数(既定 40)。半径が大きい円ほど増やす。
• 引数はここでは検証しない(0 以下の半径も積めるが意味を持たない)。
• 返り値: 追加位置の index(0 始まり)。`apply 結果の params` は
`row / col / radius、rms` は円からの半径方向残差 [px]。
穴径・ピン径の検査、円形部品の中心出しに使う。
