altair823 6188a50c1c feat(rag): fb-41 PR-3b-ii — ScriptedLm + 5 multi-hop tests + refusal hop trace + carry-over

PR-3b 의 분할 두 번째 PR — PR-3b-i 의 dynamic decide loop 위에서:

1. **ScriptedLm + ScriptedRetriever helper** (kebab-rag tests/common/mod.rs)
   per-call 다른 response 반환. decompose / decide×N / synthesize 의 각
   LLM call 을 구분하는 다단계 multi-hop 시나리오를 mock-only 로 exercise
   가능. `Vec<&str>` / `Vec<Vec<SearchHit>>` 받아 call sequence 순서대로
   emit. Send + Sync.

2. **5 multi-hop integration tests** (kebab-rag tests/multi_hop.rs 신규)
   - decide_stop_triggers_synthesize: decide [] → 즉시 synthesize
   - decide_continue_adds_more_chunks: decide ["q2"] → iter 2 retrieve + pool 확장
   - max_depth_force_stops: depth cap → forced_stop + decide LLM call skip
   - pool_chunks_dedup_by_chunk_id: 같은 chunk_id 두 sub-query 에서 1 회
   - decide_parse_failure_falls_through_to_synthesize: parse fail = graceful
     synthesize (refusal 아님, spec §9)

3. **refuse_* helper hops trace 보존** (회차 1 carry-over)
   refuse_no_chunks / refuse_score_gate 시그니처에 `hops:
   Option<Vec<HopRecord>>` 인자 추가. ask_multi_hop 의 score-gate /
   no-chunks refusal 시 누적된 hops 그대로 Answer.hops 에 보존.
   single-pass ask 는 None 전달 — wire 변동 없음 (skip_serializing_if).

4. **HopRecord doc 보강** (회차 1 carry-over)
   sub_queries 의 per-kind 의미 명시 (Decompose=initial / Decide=next-iter
   or empty=stop / Synthesize=always empty). llm_call_ms=0 의 ambiguity
   (no call vs 0ms call) doc 명시.

5. **MULTI_HOP_MAX_SUB_QUERIES_DEFAULT → _HARD_CAP rename** (회차 1 carry-over)
   const 의 의도 명확화 — config knob `multi_hop_max_sub_queries_per_iter`
   (5, prompt-side soft hint) 와 const (10, parse-side hard ceiling)
   분리. 두 layer 의 책임 doc 동기화. test 도 rename.

6. **decide guard 단순화 + preview budget doc** (회차 1 carry-over)
   parse_decompose_response 의 post-condition (Some=non-empty 보장)
   doc 명시. defensive `Some(qs) if !qs.is_empty()` →
   `decide_result.unwrap_or_default()` 단순화. decide preview 의
   snippet-only path (full chunk text 안 fetch) 의도 doc.

검증
- `cargo test -p kebab-rag -j 1` — 31 unit + 19 pipeline + 5 multi_hop
  + 3 prompt_template + 3 streaming 모두 통과.
- `cargo clippy -p kebab-rag --all-targets -j 1 -- -D warnings` clean.

Spec / plan
- design: docs/superpowers/specs/2026-05-25-p9-fb-41-multi-hop-rag-design.md
- plan: docs/superpowers/plans/2026-05-25-p9-fb-41-multi-hop-rag.md (PR-3b 단락)

다음 단계 = PR-4 (CLI --multi-hop + wire schema + error_wire).
