 **변경**:
 - `crates/kebab-config/src/lib.rs::OcrCfg` 에 `request_timeout_secs: u64` additive 필드 (`#[serde(default = "default_ocr_request_timeout_secs")]`, default `300`). 옛 config 가 필드 누락해도 그대로 파싱 + 동일 동작 (3 신규 unit test 가 default / env override / legacy parse 핀).
 - env override `KEBAB_IMAGE_OCR_REQUEST_TIMEOUT_SECS`.
-- `crates/kebab-parse-image/src/ocr.rs` 의 `REQUEST_TIMEOUT` 상수 제거. `OllamaVisionOcr::build` 시그니처가 `request_timeout_secs: u64` 추가, `new(&Config)` 는 `config.image.ocr.request_timeout_secs` 전달. `from_parts` (테스트 전용 surface) 도 동일하게 시그니처 확장 — caller 6 곳 (`crates/kebab-parse-image/src/ocr.rs::tests` 5, `crates/kebab-parse-image/tests/ocr.rs::from_parts_clamps_max_pixels_into_legal_range` 3 site) 모두 `300` 명시 갱신.

 **Edge case 동일**: `0` 은 disable 아닌 "즉시 timeout" (`Duration::from_secs(0)` 의 reqwest 의미). LlmCfg 의 doc comment 와 같은 안내가 OcrCfg field doc 에 명시.
