Create a Polygon from a list of Vec2 vertices. Vertices must form a convex polygon in counter-clockwise order.
The second parameter can be either a Vec2 local-COM offset or a Material.
This allows both the legacy 2-arg form (verts, material) and the new 3-arg
form (verts, localCOM, material, filter) — consistent with Circle and Capsule.
OptionallocalVerts: anyVertices as Array<Vec2>, Vec2List, or GeomPoly.
OptionallocalCOMOrMaterial: Vec2 | MaterialLocal centre offset (Vec2) or Material for backward compat.
Optionalmaterial: Material | InteractionFilterMaterial to assign (uses default if omitted).
Optionalfilter: InteractionFilterInteractionFilter to assign (uses default if omitted).

Cast to Body — returns the Body wrapper if this is a Body, else null.
