🌊 Saffman-Taylor Fingering — 2D Linear Instability Spectrum

2D companion of the Saffman-Taylor viscous fingering sim: a Hele-Shaw interface built from 120 Fourier modes growing at the linear-stability rate, the growth-rate curve with its cutoff and fastest wavelength, and the evolving mode spectrum.
