Returns `SpaResult` with `zenith`, `azimuth`, `sunrise`, `solarNoon`, `sunset`, and `angles`.
## Architecture
A direct port of the NREL Solar Position Algorithm (Reda & Andreas 2004) to Dart. The implementation follows the original algorithm's 142 intermediate calculations exactly. Custom zenith angles are computed in a single pass alongside the primary solar angles using the same ephemeris state.
## Compatibility
Dart SDK 3.7.0+. Works in Flutter, Dart CLI, and server-side Dart. Zero dependencies.
