Rework the simulation to fully decouple geometry from electrical transduction and support multiple geometries (membrane, cantilever). Add support for analytical stress formulations with sigma_xx, sigma_yy, sigma_xy outputs and displacement. Implement explicit piezoresistor layout for visualization, explicit piezoresistor stress integration, and full 2D visualization.
