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
