Adapt the believability/budget verification harness to the T-1033 BodyParams
strip: validation-body fixtures (Kallast/Glødberg/Marevna) no longer set the
removed orbit/star fields (orbital_period_days, axial_tilt_deg, spectral_class,
star_type). Temperature is now derived from the planet_class envelope (D-240),
so the Marevna validation note/assertion is rewritten — oceanic band [-12,28]°C
+ maritime 0.6 + standard-atmosphere greenhouse yields ~+26°C at the equator
(was a stale ~-56°C orbit-equilibrium note). Add the seed→tile golden fixture
(tests/golden/derivation_harness.json) that the determinism regression locks.
Also fmt the harness and fix one clippy lint (iter().copied().collect() ->
to_vec()) — the file predated the pre-push gate's cargo-test/clippy coverage.
