No tests for IVector0..IVector4, Magnitude(), Dot, or Cross on generated quantities

[matt-edmondson]

Summary

The branch introduces five new vector interfaces (IVector0 … IVector4) and the generator emits Magnitude(), Dot(...), and Cross(...) methods on vector quantities. None of this is exercised by tests.

Evidence

Semantics.Test/SemanticQuantityTests.cs only validates basic SemanticQuantity arithmetic; it does not test:

• IVector0/IVector1/IVector2/IVector3/IVector4 interface contracts.
• Magnitude() returning the correct V0 type, e.g. Velocity3D.Magnitude() -> Speed.
• Generated Dot like Force3D.Dot(Displacement3D) -> Energy (Generated/.../Force3D.g.cs:46+).
• Generated Cross like Force3D.Cross(Displacement3D) -> Torque3D.
• Subtraction of two V0 producing a V1 (per the generator's current choice).

Suggested next step

Add a dedicated Semantics.Test/Quantities/VectorQuantityTests.cs with cases for each generated Magnitude/Dot/Cross method, picking representative dimensions (Velocity, Force, Position, ElectricField). Use known-result vectors (e.g. (3, 4, 0) -> magnitude 5).

Resolved by #66 (commit f7b4ad7). Added Semantics.Test/Quantities/VectorQuantityTests.cs covering IVector0/IVector1/IVector3 contracts, Magnitude() extraction (e.g. Velocity3D.Magnitude() → Speed), generated Dot (Force3D.Dot(Displacement3D) → Energy), and generated Cross (Force3D.Cross(Displacement3D) → Torque3D), plus the V0–V0 absolute-difference subtraction.
