Add observation functions for 19 planetary moons across four systems:
- Galilean moons (Io, Europa, Ganymede, Callisto) via clean-room L1.2 theory
- Saturn moons (Mimas through Hyperion) via TASS 1.7
- Uranus moons (Miranda through Oberon) via GUST86
- Mars moons (Phobos, Deimos) via MarsSat
Add Jupiter decametric radio burst prediction for Radio JOVE operators:
- io_phase_angle() — Io orbital phase from superior conjunction
- jupiter_cml() — System III Central Meridian Longitude with light-time correction
- jupiter_burst_probability() — Carr et al. (1983) source regions A, B, C, D
L1.2 Galilean theory is a clean-room MIT implementation from the published
IMCCE FORTRAN coefficients. All other ephemeris libraries are MIT-licensed
extractions from Stellarium with static caching removed for PARALLEL SAFE.
All 10 regression tests pass. Extension .so grows from 2.4MB to 2.5MB.
