feat: add WELL512-based Random module with seed, float, and int methods

Browse Source 
Implement a new `random` module for the Wren language runtime, providing a `Random` class backed by the WELL512a PRNG algorithm. The module supports three seeding strategies (time-based, single numeric seed, and 16-element sequence), generates uniform floats in [0,1) and integers in the full uint32 range, and includes convenience methods for bounded ranges. The implementation adds the C foreign functions `randomAllocate`, `randomSeed0`, `randomSeed1`, `randomSeed16`, `randomFloat`, and `randomInt0`, registers them in the module registry, and includes the Wren wrapper class with constructors accepting no arguments, a number, or a sequence. The commit also adds 12 test scripts covering float/int generation, seeding reproducibility, and error handling for invalid seed types.
