Add 4 refracted rise/set functions completing the rise/set feature set:
- planet_next_rise/set_refracted: -0.569 deg threshold (refraction only,
point source — even Jupiter at opposition is only 24 arcsec)
- moon_next_rise/set_refracted: -0.833 deg threshold (refraction +
mean semidiameter, same as Sun)
Add IAU constellation identification from Roman (1987) CDS VI/42:
- 357 boundary segments covering all 88 constellations
- Precesses J2000 coordinates to B1875.0 epoch for lookup
- Two overloads: constellation(equatorial) and constellation(float8, float8)
- IMMUTABLE (compiled-in static data)
141 -> 147 SQL objects. 24 -> 25 regression suites. All 25 pass.
