PR2 of the adaptive-clearing roadmap: circle-line/circle-arc intersections as angles on the query circle (tolerance-widened per Contour::tolerance, so exact-endpoint hits survive FP; junction hits may be double-reported by design) and winding-number containment with a rigorously branch-pinned adaptive arc walk (pieces of turning <= pi/2 subtend < 3pi/2, so principal <= pi/2 pins the true branch). region_contains gives material semantics (CCW outer, CW islands). Next PR computes the exact engagement angle from these. Stacked on patman/cam-geom (#50).

Adds cam-geom point/circle queries: circle-line and circle-arc
intersections as angles on the query circle (tolerance-widened per the
contour closure contract), and winding-number containment with a
branch-pinned adaptive arc walk. These are the primitives exact
engagement is computed from.
