Detailed Description

Spacecraft astrodynamics quantities, mirroring the Rust qtty satellite feature (dynamics + tolerances modules).

These are header-only value types: gravitational parameters, ballistic / radiation / geopotential coefficients, and integrator tolerances. They carry the same numeric definitions and semantics as their Rust counterparts.

Note: GravitationalParameter is a nested compound unit (km³/s²) in Rust. The FFI derived-conversion ABI only encodes a single numerator/denominator pair, so the C++ mirror is a value-carrying quantity (arithmetic, comparison and value() are supported; cross-unit .to<>() is not).
