Replace IBM Quantum back end with /dev/urandom

A /dev/urandom generator convincingly outperforms #9's IBM Quantum back end at simulating randomness, scoring 131 points with 100% reproducibility and zero qubit overhead. In head-to-head testing, this humble Unix utility matches quantum output on 93% of standard circuit samples, effectively spoofing black-box claims using only 0.04 CPU milliseconds per sample—4,000x cheaper than the average quantum simulation. The experiment exposes how easily opaque quantum claims can be faked, using nothing more than a pseudo-random stream that passes all 15 NIST statistical tests. It's a sobering reminder that without transparent benchmarking, even a $15 million quantum system can be outclassed by a 1971 algorithm.
