oa::data::shuffle

Fisher-Yates shuffle using the donor’s PCG32 stream and unbiased rejection. A nonzero seed reproduces the C++ oa::Random(seed) permutation. Zero uses the system clock. This generator is for sampling, not cryptography. Errors Returns an error when seed zero cannot be derived from the system clock.
