PR #159 worker-1 review 의 LOW 가독성 nit 반영 — CLI stderr [hint]
line + --json hint shape 통합 test 가 없었음.
- search_plain_emits_short_query_hint_to_stderr — 빈 KB + 2자 query
→ stderr 가 "[hint]" + "3자 이상" 포함 확인.
- search_json_emits_hint_field_for_short_query — 동일 입력 --json
→ search_response.v1.hint 필드 set + 표준 advisory 문자열 정합.
- search_json_omits_hint_field_when_query_is_long_enough — 3자
query → hint 필드 absent (additive serializer 의 None 제외 동작).
wire_search_response 5 → 8 PASS.
