[T4] No test for Vec reverse iterators (masks bug #8 / B3)

[csparker247]

Summary

The incorrect return types on Vec::rbegin()/rend() (#8 / B3) are not caught by the test suite because no test exercises reverse iteration on Vec.

Required Tests

In TestVec.cpp, add TEST(Vec, ReverseIteration):

• Construct Vec3f{1.f, 2.f, 3.f}
• Iterate with rbegin()/rend(), assert order is {3.f, 2.f, 1.f}
• Repeat with crbegin()/crend() on a const Vec3f

Note

This test should be added before fixing #8 (B3) per TDD policy — it should fail to compile until the fix is applied.

Dependencies

• Should be resolved before [B3] Vec reverse iterators return wrong iterator type #8 (B3)
