nvQSP

Build and run GPU-accelerated Quantitative Systems Pharmacology (QSP) and PBPK population ODE simulations with the nvQSP library (RODAS4 stiff solver). Use this whenever the user wants to simulate compartmental PK/PBPK models, run virtual-population or batch patient simulations, do population PK variability studies, solve stiff pharmacology ODEs on an NVIDIA GPU, or mentions nvQSP, `nvqsp`, `sparse.solve`, RODAS4, or translating a pharmacology model into A0/A1/A2 coefficient form. Trigger this even when the user just describes a compartmental model ("two-compartment IV infusion across 1000 patients") without naming the library, since encoding the model into nvQSP's sparse-tensor form and getting the dosing/CSR conventions right is the hard part.
