/**
 * Error thrown when a dice expression cannot be parsed.
 *
 * Extends the built-in {@link Error}, so existing `catch (e)` / message checks
 * continue to work, while callers can now narrow with `instanceof DiceParseError`.
 *
 * @example
 * try {
 *   parse("d6@3");
 * } catch (e) {
 *   if (e instanceof DiceParseError) {
 *     // e.expression === "d6@3"
 *   }
 * }
