Documents the LLM-assisted extractor's in-scope / out-of-scope
categories derived from the first live triage pass (16 promoted,
35 rejected). Five in-scope classes, six explicit out-of-scope
classes, trust model summary, multi-model future direction.
Cleaned up stale follow-up items in next-steps.md: rule expansion
marked deprioritized, LLM extractor marked done, retrieval harness
marked done with expansion pending.
Fixed docstring timeout (45s -> 90s) in extractor_llm.py.
