RationalCodec class

A codec for encoding and decoding Rational values to and from strings.

This class provides a single, canonical seam for Rational ↔ String conversions at JSON/SQLite/persistence boundaries. It ensures consistent formatting and centralizes parsing logic.

Example:

final encoded = RationalCodec.encode(Rational.fromInt(3, 4));  // "3/4"
final decoded = RationalCodec.decode("3/4");                    // Rational(3, 4)
final safe = RationalCodec.tryDecode("invalid");                // null
