Inferred query-to-managed-world scenario

tests/test_reasoning_inferred_consumers.py wires a typed session to a separate managed world with explicit caller-driven steps — no automatic Cypher rewrite, no hidden publication. The session answers an inferred goal; the caller reconciles the managed world to those answers; corrections and retractions flow through session advance and re-publication. Every transition compares the session, the managed world and fresh recomputation, and readers pinned at older commit horizons observe the old managed state unchanged.

Retractions in the source retire the whole logical claim even when they name a superseded version, and versions committed by the managed-world writes themselves are skipped as foreign scope rather than ingested. Sampler artifact building with generation provenance is not implemented here; neither is probabilistic reasoning nor coordination with #127/#128 beyond leaving those interfaces untouched.
