chore(release): v0.3.12 — vision AI 응답 robust parse

vision model 의 markdown fence / prose 섞인 응답에서 JSON 추출 fallback.
prompt 에 title 한국어 / kebab tags / JSON-only 출력 명시 강화.

- LocalOllamaProvider: parseJsonLoose 헬퍼 (첫 { ~ 마지막 } 추출)
- visionPrompt: 4 규칙 + markdown fence 금지 명시
- 단위 +2 (fence 추출 + prose 추출)
