panchangam 0.2.0

//! Swiss Ephemeris Constants
//!
//! Re-exports common constants for planetary calculations.
//! Eliminates need for clients to hardcode these values.
//!
//! Usage in TypeScript:
//! ```typescript
//! import { Constants } from "@fusionstrings/panchangam";
//! const sunId = Constants.SE_SUN;
//! ```
