test(cad): lock construction-geometry flag with real regression tests

Browse Source

The construction flag was already honored (excluded from the extrude wire in
SketchEngine.cpp, participates in the solver, and serialized) but the existing
"construction line excluded" test was a false tripwire: its construction line
ran corner-to-corner inside the square, so the bbox was unchanged whether or not
the line was excluded.

- Strengthen that test: the construction line now runs (-30,0)->(30,0) outside
  the profile, so an exclusion regression breaks the closed wire / bbox.
- Add a serialize/deserialize round-trip test asserting construction survives.
- Lock the flag on-disk: add Sketch_Ctor to the golden fixture with a real edge
  + a construction edge, and assert both flags survive the binary recipe.

Test-only; no kernel change. Recipe version stays 2 (construction was already a
serialized field). Suite: 72 cases / 1246 assertions green.
