New tools

• Sketch tools: Extrude, Scribble, Revolve. Click polygon corners, freehand drag, or define a profile to lathe, all become editable shapes.
• Cut: Bambu-style slice along X/Y/Z with live plane preview.
• Hollow: carve any shape into a shell with adjustable wall thickness.
• Array: linear (count + spacing) and circular (count + axis + total angle).
• Ruler: 2-point distance with per-axis deltas, vertex snap with screen-space radius.
• Workplane on face: pick any face, new shapes spawn aligned to it.
• Split into loose parts: separate a mesh into its disconnected components via union-find.

Shape catalogue

• 13 primitives: Box, Cylinder, Sphere, Cone, Pyramid (now N-sided), Wedge, Roof, Tube, Torus, Polygon, Star, Heart.
• Pyramid and Polygon both get the Sides slider.
