Auto completion for locally declared types doesn't work properly

### Apache NetBeans version

Apache NetBeans 25

### What happened

No regression, already reproducible in older versions e.g NB 20.

hitting ctrl+space once will show them:


hitting it again will only show the inner class types.


As consequence, constructor completion for `Item3` and `Item4` does also not work.

### Language / Project Type / NetBeans Component

_No response_

### How to reproduce

```java
public class LocalTypeCompletion {

private record Item1(String name) {}
private class Item2{}

public void test() {

record Item3(String name) {}
class Item4{}

// new Item

// first completion contains all 4 Items,
// hitting ctrl+space again doesn't contain method-local Items
// as concequence, constructor completion does also not work.
}
}
```

### Did this work correctly in an earlier version?

No / Don't know

### Operating System

linux

### JDK

21

### Apache NetBeans packaging

Apache NetBeans binary zip

### Anything else

### Are you willing to submit a pull request?

No

Start with the Java example in the issue and reproduce completion after the first and second Ctrl+Space in NetBeans 25 on JDK 21. Trace the Java editor completion behavior for locally declared records and classes; done means method-local Item3 and Item4 remain available after repeated completion and their constructor completions work.
