feat(observer): v15 AG Native chat relay — scanChatBodies dual strategy (#632)

- Add AG Native DOM path: #conversation + .leading-relaxed.select-text
- Keep Cascade path: [data-testid=conversation-view] + [data-step-index]
- Register #632 in known-issues.md (SDK+DOM both blocked for AG Native)
- Bump version 0.5.50 → 0.5.51
- Add DOM analysis helper scripts

+### [2026-04-16] [Extension] ★ AG Native 세션 AI 응답이 Discord에 전혀 전달되지 않음 (미해결, #632)
+- **증상**: Discord에 **명령 승인 신호만 전달**되고, AI의 대화 응답/답변 텍스트는 전혀 전달되지 않음. 수십 세션에 걸쳐 지속 발생.
+- **원인 1 (SDK 경로)**: `GetCascadeTrajectorySteps(cascadeId=세션ID)` → `500 trajectory not found`. AG Native 세션은 Cascade trajectory API에 등록되지 않아 step-probe의 RT-CAPTURE가 불가능. `stepCount`가 항상 1, `delta`는 항상 0이므로 응답 캡처 루프 진입 자체가 안 됨.
+- **원인 2 (DOM 경로)**: Observer `scanChatBodies()`가 `[data-testid="conversation-view"]`, `[data-step-index]`, `.markdown-body`, `.prose` 등을 탐색하지만, **AG Native 렌더러에는 이 셀렉터가 전부 존재하지 않음** (DOM dump 확인: hasConversationView=false, hasStepIndex=false, hasMarkdownBody=false, hasProse=false, dataTestIds=[])
+- **결과**: 버튼 감지(scan→/pending)는 `button` 태그 직접 탐색이므로 정상 작동하나, AI 응답 텍스트 추출 경로는 SDK/DOM 양쪽 모두 구조적으로 차단됨
+- **해결 방향**: AG Native 채팅 패널의 실제 DOM 구조를 deep-inspect로 분석하여, AI 응답 컨테이너의 올바른 셀렉터(class/attribute)를 찾아 `scanChatBodies()` 수정 필요. SDK 경로는 AG 구조적 한계로 사용 불가.
+- **주의**: AG Native 렌더러는 `data-testid`, `data-step-index` 등 Cascade 전용 속성을 사용하지 않음. DOM 분석 시 반드시 AG 패널이 활성화된 상태에서 dump를 취득해야 함 (설정 페이지와 혼동 금지)
+- **Vikunja**: #632

 ### [2026-04-16] [Extension] 터미널 출력(stdout) 텍스트가 명령어로 Discord에 전송 (v0.5.50)
 - **증상**: Discord에 `cmd="No extension.log found"`, `cmd="AG CLI not found..."`, `cmd="Log found: C:\..."` 등 터미널 **출력** 텍스트가 명령어로 전송됨
 - **원인**: Observer가 code 블록 2개를 감지: (1) 프롬프트+명령어 → JUNK_CODE_RE로 스킵, (2) 터미널 출력 → 유효한 code로 판단 → description에 포함. http-bridge enrichment에서 description에 prompt marker(`>`)가 없으면 rawDesc 전체를 enrichedCmd로 채택
