z-u-v-blockchain-riemann: Initial Release: Z-U-V Blockchain Consensus with Riemann Zeros

Z-U-V three-space dynamics with Riemann zero encoding for blockchain consensus. Complete simulation with 100 nodes, each assigned a unique Riemann zeta zero γ. Produces 201 blocks in 200 rounds with 100/100 active nodes. Includes attack detection (V-space) via γ distribution analysis, reputation-weighted voting (U-space), and dynamic block sizing (Z-space) via f-Shrink operator. Core constant f≈0.47454 from ln f+(π/2)f=0. Successfully detects Sybil attacks with 20 fake nodes (7/15 anomaly bins).
