Add diagonal_win.dsn: a 45-degree pin-to-pin net with a keepout placed inside the diagonal's bounding box but clear of the true thin copper. Orthogonal routing connects it with a Manhattan-length staircase (1600000); diagonal routing replaces that with a single 45-degree trace at the ideal hypotenuse length (1131371) -- a 29% reduction -- DRC-clean via the search tree and via an independent reconstruction of the emitted 45-degree copper's clearance octagon. test_exact_clearance_is_load_bearing shows the keepout overlaps the coarse bounding box but not the exact octagon, so the exact clearance (not the box) is what lets the diagonal route. Determinism, endpoints-on-pads, valid SES, and diagonal-off-equals-orthogonal (additive, over four fixtures) are covered.
