FormingWorlds/Zalmoxis: Version 26.01.06

This release introduces a major enhancement to Zalmoxis with the implementation of the RTPress equation of state (EOS), valid up to 1 TPa, incorporating melting curves from Wolf & Bower (2018). While the core continues to be modeled using the Seager et al. (2007) EOS for iron, the mantle can now be treated as fully solid, partially molten, or fully molten, depending on a user-specified temperature profile. These updates enable more realistic modeling of high-pressure planetary interiors and allow for a self-consistent treatment of melting effects in the mantle.
