Module prelude 

Common imports for ergonomic usage.

This prelude re-exports the primary types and common constants: Matrix, DeterminantWithErrorBound, Vector, Lu, Ldlt, Tolerance, and LaError. Its typed error categories include ArithmeticOperation, FactorizationKind, InvalidToleranceReason, NonFiniteLocation, NonFiniteOrigin, PositiveSemidefiniteViolation, SingularityReason, and UnrepresentableReason. It also re-exports DEFAULT_SINGULAR_TOL, MAX_STACK_MATRIX_DISPATCH_DIM, and try_with_stack_matrix! for runtime-to-const matrix dispatch. Advanced custom-filter code should import ERR_COEFF_2, ERR_COEFF_3, and ERR_COEFF_4 explicitly from the crate root; those raw coefficients intentionally stay out of the prelude.

When the exact feature is enabled, DeterminantSign, ExactF64Conversion, BigInt, and BigRational are also re-exported. ExactF64Conversion converts an already-computed exact determinant or solution under either the strict or explicitly rounded binary64 contract, without repeating exact elimination. The number types let callers construct expected exact values without adding num-bigint / num-rational to their own dependencies. The most commonly needed num-traits items are re-exported alongside them: FromPrimitive for BigRational::from_f64 / from_i64, ToPrimitive for BigRational::to_f64 / to_i64, and Signed for .is_positive() / .is_negative() / .abs().
