// DONUT command — create a filled circular ring (thick LwPolyline).
//
// A donut is an LwPolyline with:
// - 2 vertices at (cx ± r_avg, 0), both with bulge = 1.0 (two 180° CCW arcs)
// - constant_width = (outer - inner) / 2
// - is_closed = true
//
// Workflow:
// 1. Type inner diameter (or 0 for a filled circle)
// 2. Type outer diameter
// 3. Click center point(s); Enter to finish
// DONUT creates a ring as a closed, constant-width LwPolyline.
