feat(phase2b): P2b.2 — bounded Editorial_Loop (#179, v0.29.0)

Additive: iterative editor↔writer loop bounded by editorial_max_rounds (default 3), escalates to Review Queue on exhaustion, records each round; behind interface, Authority-only (live path untouched). Also deletes dead class-research-dedup.php + repairs ARCHITECTURE.md. QA APPROVE 16035fa; CI green (VPS-verified).
