fix(extension): Retry auto-approve 흐름 복구 + Observer 형제 탐색 + thinking 필터링 (v0.5.79)

- WS response 파일에 _from_ws 마커 추가하여 processResponseFile 삭제 방지
- extractContextFromNearby에 sibling 탐색 추가 (AG Native DOM 구조 대응)
- thinking 블록 (max-h-[200px]) 필터링으로 내부 사고 릴레이 차단
- DOM 탐색 depth 5→10 확대 + pre.font-mono 우선 탐색
- 사용자 메시지 셀렉터 (.select-text.rounded-lg) 추가
