DCRP-41: Planar-Covariance Shape Disk and Moving Pancake-Jet Normal Form

Derives the exact two-dimensional disk equation for the normalized in-plane covariance, proves that zero shape action forces pointwise isotropic affine stretching on the vorticity plane, and on this equality branch reconstructs the full three-dimensional affine tensor as a moving pancake jet.
