jyvikoandClaude Opus 5.5 6d9452ad84 Verification oracle: tests/oracle cases, cargo xtask oracle, fixtures, docs/oracle.md, CI job

The oracle binary (modelcraft-testkit) runs each case's recipe through the
command engine, measures its quantities by JSON pointers into step outputs
or commands, compares them with the cited references and the frozen
fixtures, and writes docs/oracle.md. 20 theory cases (patch tests of every
solid element, Timoshenko cantilevers, Lame, Kirsch, beam frequencies,
torsion and bending through couplings, explicit waves and impact, CDT
invariants), 8 published benchmarks (MacNeal-Harder patch, straight and
curved cantilevers, thick cylinder, Scordelis-Lo with solids, NAFEMS LE1,
LE10, FV32) and 10 pending cases with citations.

Cantilever under a tip load, Timoshenko deflection (tet10)

A 10 × 1 × 1 bar of tet10 elements (20 × 2 × 2) clamped at x = 0 with a total force of 1 in −z spread over the free end (E = 1000, ν = 0, so no Poisson coupling at the clamp). Timoshenko beam theory gives δ = PL³/(3EI) + PL/(κGA) = 4 + 0.024 = 4.024.
