1.0.0 - 2026-03-08

Added

• qiblaAngle(lat, lng) computes the initial bearing to the Ka'bah in degrees.
• compassDir(bearing) returns an eight-point compass abbreviation (N, NE, E, etc.).
• compassName(bearing) returns the full compass direction name (North, Northeast, etc.).
• qiblaGreatCircle(lat, lng, [steps]) generates waypoints along the great circle to the Ka'bah via spherical linear interpolation.
• distanceKm(lat1, lng1, lat2, lng2) computes haversine distance between two points.
• Constants: kaabaLat, kaabaLng, earthRadiusKm.
• RangeError validation for all coordinate inputs.
