[Bug]: IsEquivalentTo broken for value types

[davidmehren]

Description

Value Types like ValueTuple are compared using Equals during IsEquivalentTo, which is incorrect, as these can contain objects that contain references.

Expected Behavior

Tuples that contain structurally equal objects are asserted as equal, even when they contain non-record reference types.

Actual Behavior

Tuples that contain structurally equal objects are asserted as non-equal

Steps to Reproduce

See reproducer at https://github.com/davidmehren/TUnitIgnoreTypeRepro/blob/broken-equivalence/Tests.cs

Thing.Numbers is a non-record reference type inside a record and needs to be compared structurally.

IDE-Specific Issue?

• I've confirmed this issue occurs when running via dotnet test or dotnet run, not just in my IDE
