011 array literal bindings

// TEST: Array literal with flow bindings
//
// Koru array literals can reference bindings from the flow scope.
// This is essential for collecting results from multiple events.
//
// Expected: Compiles and runs, array contains bound values

~event getValue { id: i32 } -> i32
