It is not to recognize exported variables when transforming namesapce

[chirsz-ever]

example code:

export {}
namespace foo {
    export var bar = 'baz';
}
namespace foo {
    bar = 'foo';
}

TypeScript output:

export {};
var foo;
(function (foo) {
    foo.bar = 'baz';
})(foo || (foo = {}));
(function (foo) {
    foo.bar = 'foo';
})(foo || (foo = {}));

amaro ouput (with amaro.transformSync(src, { mode: "transform" })):

export { };
(function(foo) {
    foo.bar = 'baz';
})(foo || (foo = {}));
(function(foo) {
    bar = 'foo';
})(foo || (foo = {}));
var foo;

I didn't notice the statement "Amaro is a wrapper around @swc/wasm-typescript". If you think #393 and #394 should be SWC issues, feel free to close them.
