fn simple_eci_to_geodetic_latlon(position_eci: &arika::SimpleEci, epoch: &[arika::epoch::Epoch<arika::epoch::Utc>](../../../../arika/api/structs/epoch/)) -> (f64, f64)

Convert a simple-path ECI position to WGS-84 geodetic latitude and longitude [degrees].

The input position_eci is a Vec3<SimpleEci> — the phantom-typed marker produced by the Phase 1–3 simple rotation path. The rotation to SimpleEcef uses naive ERA (epoch.gmst() on a UTC epoch, equivalent to assuming dUT1 = 0). Accuracy is bounded by the ~0.9 s dUT1 drift, producing up to ~24 km longitude error at the equator.
