…n EOS The EOS was incorrectly normalizing the total heat capacity sum_ni_fi_over_2 by dividing by the particle count before using it for internal energy and temperature calculations. This made the internal energy per unit mass ~1/n_total times too small, causing the ionized gas temperature to be ~140x too low for the DTypeFront test (n_H=139.9), giving an expansion speed of ~750 m/s instead of the expected ~10 km/s. Fix: separate the unnormalized sum_ni_fi_over_2 (total heat capacity, used for e, T, dedT) from fi_over_2_avg = sum_ni_fi_over_2 / sum_Abarinv (per-particle average, used for pressure, cs, G). Also fix electron mass: spmasses[Electron] was set to proton mass; now correctly set to C::m_e = 9.109e-28 g. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Add radiation variables to enable photochemistry. Bug fix: Last character of eos file is not read if it doesn't end with newline character.
