Tap-to-measure (issue #68)

ViewportController.measurementMode (.distance / .angle / .radius) now actually drives interaction. While a mode is active, taps on geometry accumulate world-space surface points and commit a ViewportMeasurement (rendered by the existing MeasurementOverlay). Previously the property was published but consumed by nothing.

Added

  • Point order per mode: .distance → start, end (2 taps); .angle → armA, vertex, armB (3 taps); .radius → center, edge (2 taps).
  • ViewportBody.worldHitPoint(ray:triangleIndex:) — reconstructs the picked surface point in world space, respecting the body's transform.
  • Controller: pendingMeasurementPoints, addMeasurementPoint(_:), handleMeasurementPick(...), cancelPendingMeasurement(), clearMeasurements(), static pointCount(for:). Mode change clears pending; face picks only; selection stream untouched.
  • MeasurementMode is now Equatable.

Tests

  • New MeasurementModeTests (14). 160 tests total, all green.

Additive and source-compatible.
