Tool RAG: pin the keep set (harness, Skill, deferred) in a test

When ARTEX_TOOL_RAG is enabled, AugmentTools keeps the core tools plus the
top-k (ARTEX_TOOL_RAG_TOPK, default 12) BM25-ranked bound tools for the
worker intent / planner goal. Runs after ToolResolve, so it only removes;
falls back to the full list on empty query, catalog under 20, or scorer error.
