🌡️ Steady-State Temperature Distribution — Laplace Equation Solver (2D)

Solve Laplace's equation for the steady-state temperature field of a 2D rectangular plate. Set independent boundary temperatures on the top, bottom, left, and right edges and watch Gauss-Seidel relaxation converge to the equilibrium distribution. No time evolution — this is the pure boundary-value problem, distinct from a live transient diffusion simulation.
