* kg(postgres_impl): ensure AGE extension is loaded in session and configure graph initialization
* dev: add hybrid dev helper scripts, Makefile, docker-compose.dev-db and local development docs
* feat(dev): add dev helper scripts and local development documentation for hybrid setup

- Tests updated to match API changes (tenant routes & document routes)
- Add logs and scripts for inspection and audit
• Add CJK analyzer for Chinese text
• Auto-detect Chinese characters
• Recreate index if needed
• Separate Chinese/Latin search logic
• Improve fallback for Chinese queries
Add get_all_nodes() and get_all_edges() methods to Neo4JStorage, PGGraphStorage, MongoGraphStorage, and MemgraphStorage classes. These methods return all nodes and edges in the graph with consistent formatting matching NetworkXStorage for compatibility across different storage backends.
- Update extract_entities function in operate.py to use 1.0 as default weight
- Fix Neo4j implementation to use 1.0 instead of 0.0 for missing edge weights
- Fix Memgraph implementation to use 1.0 instead of 0.0 for missing edge weights
- Ensures consistent non-zero default weights across all graph storage backends
- 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
