Add A_Expr.rexpr context transformation for Integer nodes

- Add context propagation to A_Expr.rexpr field
- Add context propagation to List.items field
- Handle empty Integer objects {} -> {ival: -1} in A_Expr.rexpr contexts
- Current pass rate: 60.9% (157/258 tests)
- Successfully handling arrayBounds and A_Expr.rexpr transformations
