//! Symbolic Mathematics Module — Rational Arithmetic Domain
//!
//! Provides exact rational arithmetic through RationalNumber and tiered operations.
//! All legacy symbolic tracking (SymbolicAdaptiveFixedPoint, Symbol, etc.) has been
//! archived — FASC uses RationalNumber directly via StackValue::Symbolic.
