Feature A: GiST index for equatorial type with KNN ordering (<-> strategy 15). 24-byte float-precision spherical bounding box, RA-wrapping aware merge/split, Vincenty lower-bound distance for correct KNN pruning. Apollo-hardened with epsilon-widened bounds, circular-aware picksplit, compile-time size assertions. Feature B: 4 new DE moon equatorial functions (galilean_equatorial_de, saturn_moon_equatorial_de, uranus_moon_equatorial_de, mars_moon_equatorial_de). Same-provider rule enforced, transparent VSOP87 fallback. 120 -> 132 SQL objects. 22 regression suites passing.
