fix: improve Java annotation handling in listCodeDefinitionNames

- Made annotation detection more generic (not hard-coded for specific annotations)
- Skip lines starting with @ when looking for method signatures
- Filter out standalone annotation definitions
- Handles any number of annotations on methods/fields dynamically

Fixes #7330
