"Hello World" program from README doesn't work

I have the following eo program:

```
# Just prints hello.
[args] > app
  QQ.io.stdout > @
    "Hello, world!\n"
```

I run

```
eoc --easy --parser=0.52.0 --home-tag=0.52.0 dataize app
```

I get the error:

```
Couldn't find object 'Φ.app'
JVM failed with exit code #1
```

Expected behaviour: 
```
Hello, world!
```

`eoc` version:

```  
0.28.1
```

System:

```
Ubuntu 24.04.2
```
