Can't catch exceptions when I upgrade version from 2023-12-09 to 2024-01-13

    LOGW("### JS START ###");
    Js_Engine.env = env;

    string testCode = "print('hello from code.'); throw new Error('error from code!')";

    JSRuntime *rt = JS_NewRuntime();
    js_std_init_handlers(rt);
    JSContext *ctx = JS_NewContext(rt);

    JSValue global_obj = JS_GetGlobalObject(ctx);
    JS_SetPropertyStr(ctx, global_obj, "print", JS_NewCFunction(ctx, jsf_print, "print", 1));
    JS_FreeValue(ctx, global_obj);

    JSValue jsValue = JS_Eval(ctx, testCode.c_str(), testCode.length(), "main",
                              JS_EVAL_TYPE_MODULE);

    JSValue error = JS_GetException(ctx);

    double dValue;
    JS_ToFloat64(ctx, &dValue, jsValue);

    LOGE("isError: %d isException: %d dValue:%f", JS_IsError(ctx, error), JS_IsException(error), dValue);

    JS_FreeValue(ctx, error);

    JS_FreeValue(ctx, jsValue);
    JS_FreeContext(ctx);
    JS_FreeRuntime(rt);

    LOGW("### JS END ###");

output:

### JS START ###
hello from code.
isError: 0 isException: 0 dValue:nan
### JS END ###

Running on an Android device, through jni calls, I did not make any changes to the source code
On the version 2023-12-09, running errors can be caught normally

run same code on 2023-12-09 version output

### JS START ###
hello from code.
isError: 1 isException: 0 dValue:nan
### JS END ###

Reproducible on linux, but only when using eval with JS_EVAL_TYPE_MODULE, e.g. JS_EVAL_TYPE_GLOBAL works as expected

[andrieshiemstra]

ah, since module eval now support top-level await (see https://bellard.org/quickjs/Changelog) evalling a module actually returns a Promise.. my bet is that Promise will resolve to an error if code throws error....

-- edit --

confirmed, eval_module returns a promise which is rejected to the error thrown in code..

So the CLI(qjs) should be updated too. See #363 (comment)
