MagneticDeclinationProvider

Provides magnetic declination values for a given location and time.

Magnetic declination is the angle between true north and magnetic north at a specific geographic location. This abstraction allows for testability and future extensions (e.g., caching, model updates, alternative data sources).

Typical values: -20° to +20° depending on location (varies ~6° per 1000 km).
