v1.9.0 — surface deviation + invalid-shape loading (inspection/measurement)

Measurement & inspection improvements, with Node↔Swift parity restored via OCCTSwiftScripts v1.4.0.

New

• measure_deviation — directed + symmetric surface deviation (one-sided / symmetric Hausdorff) between two bodies. The metric for certifying a reconstruction against its source mesh; measure_distance is minimum-only. Reports {max, rms, mean, worstPoint} per direction + symmetricHausdorff. (#41, #46)
• compute_metrics → boundingBoxOptimal — opt-in tight extent (BRepBndLib::AddOptimal); the default Bnd_Box over-reports curved B-spline geometry. (#44, #45)
• read_brep / import_file → allowInvalid — load a topologically invalid / loose-face shape (an in-progress reconstruction) into the scene so the analysis tools can measure it. (#41 Gap 2, #48)

Fixed

• execute_script pinned a pre-1.0 OCCTSwiftScripts → stale OCCTSwift; now tracks the server cohort. (#42, #43)

Node parity

• measure_deviation, compute_metrics boundingBoxOptimal, and read_brep / import_file allowInvalid are now in both servers (Node wraps the new occtkit verbs). Node tool count 36 → 37. (#47, #48)

Cohort

OCCTSwift 1.8.0, OCCTSwiftScripts 1.4.0.
