Hakan Seven	6fd740e38f	feat: ellipse arc endpoint snap and LWPolyline arc midpoint grips ... Partial ellipse arcs now populate key_vertices with both endpoints so Endpoint snap works correctly. LWPolyline arc segments (bulge ≠ 0) get a diamond grip at the arc midpoint; dragging it recomputes the segment bulge via circumcircle of start/mid/end, giving interactive arc editing.
