Module orientation 

Two-axis projective orientation fit at a chessboard corner.

The detector lifts each subpixel corner to an AxisFitResult that carries the two local grid-axis directions, their per-axis 1σ angular uncertainties, and a residual RMS. The actual fit is pluggable via OrientationMethod.

Two public entry points are provided:

• fit_axes_at_point (image input) — samples the ring at (cx, cy) and dispatches to the chosen method.
• fit_axes_from_samples (presampled input) — accepts the 16 ring samples directly; convenient for unit tests and for the orientation benchmark when ring sampling is decoupled.

New algorithm variants plug into the OrientationMethod enum without breaking SemVer thanks to the #[non_exhaustive] attribute.
