🌍 Earth Mantle Convection: Rayleigh Number, Plumes and the Blankenbach Benchmark

A cutaway slice of the Earth with a live thermal-convection solver in the mantle: raise the Rayleigh number past the 657.5 onset, inject plumes and cold slabs, and verify the solver against the analytic growth rate and a published benchmark.
