Soumil Rathi 78cc11ef1f fix: restore lmstudio/deepseek providers in TS factory, add langchain to extras 
- Restore LMStudioEmbedder, LMStudioLLM, DeepSeekLLM in TS factory.ts
  (accidentally removed during graph store cleanup — unrelated to graphs)
- Add langchain>=0.1.0 to Python extras dep group (was transitively
  provided by langchain-neo4j in the removed graph group, still needed
  by mem0/llms/langchain.py and mem0/embeddings/langchain.py)
- Add pytest.importorskip("langchain") to test_langchain.py for graceful
  skip when langchain isn't installed

Soumil Rathi 1a2edf739d fix: delete graph test files that import removed graph modules 
These test files import mem0.memory.graph_memory, kuzu_memory,
memgraph_memory, apache_age_memory, and mem0.graphs.neptune which
were deleted in the graph store removal commit.

Soumil Rathi 66446bd118 fix: address reviewer bugs — metadata mutation, test args, embedding dict, output_format 
1. Fix _create_procedural_memory metadata mutation: use spread operator
   instead of in-place dict assignment (sync + async)
2. Fix test_add assertion: remove trailing None arg that doesn't match
   _add_to_vector_store(messages, metadata, filters, infer) signature
3. Restore output_format: "v1.1" in TS client search payload as fallback
4. Fix infer=False path: pass {text: embedding} dict to _create_memory
   instead of raw embedding list to avoid redundant embed() calls (sync + async)

Soumil Rathi b9e26acf4d merge: integrate main into feat/v3-pipeline + port AsyncMemory to v3 
Merge 190 commits from main including:
- limit→top_k rename across all vector store APIs
- custom_fact_extraction_prompt→custom_instructions rename
- enable_graph flag removal (use self.graph truthiness)
- US/Pacific→timezone.utc normalization
- 18 Category A bug fixes (partial updates, graph cleanup on delete,
  telemetry gating, metadata mutation prevention, filter operator
  merging, delete timestamps, actor_id preservation, etc.)

Conflict resolutions:
- openai.py: merged _pass_dimensions_to_api with embed_batch
- milvus.py: merged partial-update logic with BM25 text field
- qdrant.py: took main's enhanced _create_filter, merged BM25
  sparse vectors with partial-update endpoints
- test_main.py: adopted main's test structure, removed obsolete
  test_custom_prompts, kept hybrid search over-fetch assertion

AsyncMemory v3 port (full parity):
- Rewrote AsyncMemory._add_to_vector_store with the same 8-phase
  batch pipeline as sync Memory (single LLM call, batch embed,
  hash dedup, batch persist, batch entity linking, message saving)
- All blocking calls wrapped in await asyncio.to_thread()
- Moved _build_session_scope to module level for shared access

Soumil Rathi a33c557a25 feat(oss): port v3 pipeline with hybrid search, entity extraction, and additive scoring 
Replace the 2-LLM-call add pipeline with a single-pass additive extraction
using ADDITIVE_EXTRACTION_PROMPT. Memories now accumulate (ADD-only) instead
of being updated/deleted during extraction.

Search pipeline upgraded to hybrid scoring combining three signals:
- Semantic similarity (vector search)
- BM25 keyword matching (native per vector store, 15 stores supported)
- Entity boost (spaCy NER with entity collection linking)

Combined score = (semantic + bm25 + entity_boost) / max_possible, where
max_possible adapts based on which signals are active.

Key changes:
- Add spaCy-based lemmatization for BM25 keyword search
- Add spaCy-based entity extraction (PROPER, QUOTED, COMPOUND, NOUN types)
- Add entity store as second vector collection ({collection}_entities)
- Add native keyword_search() to 15 vector store adapters
- Add batch embedding support (embed_batch) for OpenAI and Azure OpenAI
- Add message persistence in SQLite (rolling window of 10 per scope)
- Add additive scoring with adaptive normalization
- Add observation_date parameter to add()
- Add custom_instructions config field
- Default search threshold changed to 0.1
