Centralized configuration constants for LightRAG.

This module defines default values for configuration constants used across
different parts of the LightRAG system. Centralizing these values ensures
consistency and makes maintenance easier.

feat: Centralize configuration and update defaults This commit introduces `lightrag/constants.py` to centralize default values for various configurations across the API and core components. Key changes: - Added `constants.py` to centralize default values - Improved the `get_env_value` function in `api/config.py` to correctly handle string "None" as a None value and to catch `TypeError` during value conversion. - Updated the default `SUMMARY_LANGUAGE` to "English" - Set default `WORKERS` to 2 2025-05-06 22:00:43 +08:00			`"""`

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 2025-06-25 12:37:57 +08:00			`# Separator for graph fields`
