tests(stdlib): reorganize and expand StandardLibrary tests

Browse source 
- Switch tests to use Initializer.InitializeAll for setup
- Split stdlib tests by category: Angle, Rounding, Trig (incl. hyperbolic), NumberTheory, Random
- Add comprehensive tests invoking functions via InputInterpreter.Interpret()
- Register Bernoulli in Initializer so random tests cover
