Add v0.13.0: nutation, make_equatorial constructor, rise/set predictions

Browse Source 
Integrate IAU 2000B nutation (~9 arcsec) into the solar system observation
pipeline via precess_and_nutate_j2000_to_date(). Affects all planet, star,
moon, and small body RA/Dec and az/el values. Satellite SGP4/TEME pipeline
unchanged.

Add make_equatorial(ra_hours, dec_deg, distance_km) constructor to replace
error-prone text literal casts.

Add 8 rise/set prediction functions (planet_next_rise/set, sun_next_rise/set,
moon_next_rise/set, sun_next_rise/set_refracted) using bisection algorithm
adapted from satellite pass prediction. Returns NULL for circumpolar and
polar night edge cases.

Fix DE fallback test fragility: replace exact float equality with tolerance
comparisons to handle GCC LTO inlining divergence across translation units.

132 -> 141 SQL objects. 22 -> 24 regression suites. All 24 passing.
