jyvikoandClaude Opus 5.5 96c9992c92 oracle: 2D cases (Kirsch plane stress, Lamé plane strain and axisymmetric, rotating disc and cylinder, NAFEMS LE1 with quad8) and J2 uniaxial explicit

The pending 2D LE1 case becomes a real one; the plasticity cases stay
pending with what they still need (static J2 for the collapse pressure,
the transcribed measurements for the Taylor bar).

Thick-walled cylinder under internal pressure, axisymmetric (Lamé)

The same cylinder as an axisymmetric slice r ∈ [10, 20], 0 ≤ y ≤ 1 (y is the axis), held axially on both faces so ε_z = 0 (the plane strain state of a long cylinder); one quad8 patch of 8 × 1 elements.
