fix(physics): correct DESI constants to match published DR1/DR2 values
DESI DR1 (arXiv:2404.03002, 2024): w0 = -0.827 +- 0.063, wa = -0.75 +- 0.29 Om = 0.295 +- 0.008, H0 = 68.52 +- 0.50 DESI DR2 (arXiv:2503.14738, 2025): w0 = -0.838 +- 0.055, wa = -0.59 +- 0.25 Om = 0.2975 +- 0.0086, H0 = 68.26 +- 0.45 Model predictions vs DR1 (all within 1s): w0: calibrated match (residual = 0) wa: -0.55 vs -0.75 (residual = +0.20, 0.69s) Om: 0.290 vs 0.295 (residual = -0.005, 0.63s) s8: 0.812 vs 0.812 (exact match)
