geometry op• 数据种类:points → primitive
• 调用: import fullseye as fs; fs.ledger.fit_box3(points) -> 'dict'(要直接调用实现,import measure3d; measure3d.fit_box3(points) -> 'dict';从台账取用则 ops3d.get("fit_box3"))
用 PCA 拟合有向长方体(快速、抗噪;与 `obb` 同一构造)。

`pcseg.obb but with the measure`-style dict). Axes are the principal
directions of the point spread; extents come from the projected span. Returns
`center (cd/cr/cc), axes` (3, 3 — unit ROW vectors, depth/row/col
components), sorted half-extents `l1 >= l2 >= l3, full size, volume`,
`corners` (8, 3), and the RMS point-to-box-surface distance. For the true
minimum-volume box use `smallest_box3. Raises ValueError` on < 4 points
or a degenerate (flat) set.
