Add Support for Java Annotations

[Shashankss1205]

• Description: Metadata added to code elements, used by the compiler or frameworks.
• Graphing Strategy: Model with an ANNOTATES relationship from an :Annotation node to the code element it modifies.

Implementation Steps

This requires an :Annotation node type and an ANNOTATES relationship.

1. Modify the Java Parser (.../languages/java.py)

   • Add queries to find both annotation definitions and their usage.
   • Create _find_annotations (for definitions) and _find_annotation_applications methods.
   • Return results under keys "annotations" and "annotation_applications".

2. Update the Generic Graph Builder (.../tools/graph_builder.py)

   • Add the :Annotation node type following the standard procedure (schema and item_mappings).
   • Add a new section in add_file_to_graph to process annotation_applications and create the ANNOTATES relationships between the :Annotation node and the annotated element.
