Adds five new kernel-free functions using Meeus Ch. 47/48 approximations,
replacing suncalc as the moon data source in the acamarata stack.
- getMoonPosition(date, lat, lon, elevation?) — topocentric az/alt/distance +
parallactic angle via WGS84 geodetic model and Bennett refraction
- getMoonIllumination(date) — illumination fraction, phase cycle position,
bright limb angle, isWaxing via Meeus Ch. 47/48
- getMoonPhase: adds phaseName ("Waxing Crescent") and phaseSymbol ("🌒")
fields to MoonPhaseResult
- getMoonVisibilityEstimate(date, lat, lon, elevation?) — kernel-free Odeh
V-parameter crescent visibility estimate; returns zone A-D, V, ARCL, ARCV, W
- getMoon(date, lat, lon, elevation?) — convenience wrapper combining all four
kernel-free functions into a single MoonSnapshot result
New types: MoonPosition, MoonIlluminationResult, MoonVisibilityEstimate, MoonSnapshot
98 tests (78 ESM + 20 CJS), typecheck clean, zero build warnings
