- _get_all_from_vector_store: top_k -> limit (2 missed occurrences)
- test_empty_llm_response_fact_extraction (sync+async): add
db.get_last_messages mock returning [], set custom_instructions=None,
fix log assertion to use record.message not record.msg
- test_thinking_tags (sync+async): add embed_batch mock, db mock
with get_last_messages=[], set custom_instructions=None
Root cause: v3 pipeline calls self.db.get_last_messages() and
self.embedding_model.embed_batch() which weren't mocked, causing
the pipeline to silently fail before reaching the LLM call.
