091f2b42c3 feat(performance): Optimize document deletion with entity/relation index 
- Introduces an index mapping documents to their corresponding entities and relations. This significantly speeds up `adelete_by_doc_id` by replacing slow graph traversal with a fast key-value lookup.
- Refactors the ingestion pipeline (`merge_nodes_and_edges`) to populate this new index. Adds a one-time data migration script to backfill the index for existing data.

da46b341dc feat: Optimize document deletion performance 
- To enhance performance during document deletion, new batch-get methods, `get_nodes_by_chunk_ids` and `get_edges_by_chunk_ids`, have been added to the graph storage layer (`BaseGraphStorage` and its implementations). The [`adelete_by_doc_id`](lightrag/lightrag.py:1681) function now leverages these methods to avoid unnecessary iteration over the entire knowledge graph, significantly improving efficiency.
- Graph storage updated: Networkx, Neo4j, Postgres AGE

Remove graspologic pip installation that no longer seems to be used 
As far as I can tell this is no longer actually used and its usage was removed in this commit:
83353ab9a6 (diff-a346bcfb05aab0cc0c0baa6018976f4efab339e8cade9f6f8fb658fcbd54ae2e)

Our systems are flagging this package as having a dependency on a package with a less permissive license so I would appreciate if it can be removed if its no longer needed.  Let me know if that is not the case.
