Fixes #1075. sketch.constraint.symmetry takes a centre point (the origin or any sketch point) as well as a line; the Symmetry tool's third pick may be the origin point or the sketch's own X/Y origin axis. Checked on main + this branch: cargo check --workspace, the engine cmd::sketch tests (257) and the UI symmetry pick tests.
