wai-quantum 0.3.21

A deterministic quantum stack in pure Rust: byte-exact circuit simulation (statevector / stabilizer / tensor-network MPS / sparse-Pauli backends), error mitigation, qLDPC decoding, noise learning, circuit-equivalence proofs, a phasor interference-ML layer, information-theoretic limits, noisy channels and state tomography, and signed energy-accounted receipts. No QPU, no cloud, no system libraries — identical results native, in the browser, and as a WASI component at the edge.
