• Convert CompressibleEquations to MPAS-style dry-density (ρᵈ) evolution

  Prognose dry-air density ρᵈ instead of total density, following the MPAS-A dry-coupled formulation. dynamics_density now returns ρᵈ — the coupling density that weights the flux variables (momentum ρu = ρᵈu, thermodynamic ρθ = ρᵈθ), divides velocity/θ, and is advanced by continuity. The total air density ρ = ρᵈ + Σρˣ is a diagnosed field (total_air_density, stored on the dynamics) used wherever total mass enters the physics: moisture mass-fraction recovery, scalar/water advection carriers, the equation of state, buoyancy, and saturation.

Closed issues:

• Substepping with terrain-following coordinates: implementation plan (#673)
• Possible bug in bulk drag formulation when using filtered veloctites (#698)
• ZeroMomentCloudMicrophysics loses latent warming on rain-out — root cause, the compressible-core constraint, and two paths forward (#772)
• Reactant raise=true: cannot raise vector<2xf64> gas-constant llvm.mlir.constant to stablehlo (acoustic_wave AD example) (#796)
• NaNs & Floating point exception following Reactant@0.2.267 (#801)
