### Added
- `getMoonPosition(date, lat, lon, elevation?)` — topocentric Moon azimuth, altitude, distance,
- `getMoonPosition(date, lat, lon, elevation?)`: topocentric Moon azimuth, altitude, distance,
and parallactic angle via Meeus Ch. 47 (no kernel required, ~0.3° accuracy)
- `getMoonIllumination(date)` — illumination fraction, phase cycle position, bright limb
- `getMoonIllumination(date)`: illumination fraction, phase cycle position, bright limb
position angle, and waxing/waning flag via Meeus Ch. 47/48 (no kernel required)
- `getMoonVisibilityEstimate(date, lat, lon, elevation?)` — quick kernel-free Odeh crescent
- `getMoonVisibilityEstimate(date, lat, lon, elevation?)`: quick kernel-free Odeh crescent
visibility estimate using Meeus positions; returns V parameter, zone (A-D), ARCL, ARCV, W
- `getMoon(date, lat, lon, elevation?)` — combined convenience wrapper returning phase,
- `getMoon(date, lat, lon, elevation?)`: combined convenience wrapper returning phase,
position, illumination, and visibility estimate in a single call
- `phaseName` and `phaseSymbol` fields on `MoonPhaseResult` — human-readable name
- `phaseName` and `phaseSymbol` fields on `MoonPhaseResult`: human-readable name
(e.g. "Waxing Crescent") and moon phase emoji (e.g. "🌒")
- `MoonPosition`, `MoonIlluminationResult`, `MoonVisibilityEstimate`, and `MoonSnapshot`
