fix(extension): v0.3.7 — file_permission 3-button 주입 + active_project.lock 제거

- writePendingApproval()에서 step_type=file_permission일 때 자동 3-button 주입
- active_project.lock 메커니즘 제거 (멀티 프로젝트 동시 사용 지원)
- step_probe auto-resolve에 project_name 필터 추가
- known-issues 2건 추가

 - **원인**: 봇이 file_permission pending에 대해 `runCommand.confirm` RPC를 전송 (file_permission이 아닌 잘못된 interaction type). 또는 오래된 pending에 대해 봇이 자동 처리
 - **해결**: (1) pending의 `step_type`이 `file_permission`일 때 extension이 `filePermission` RPC 사용 (이미 구현됨), (2) DOM Observer의 file_permission 감지 → `buttons` 배열 + `step_type: 'file_permission'` 명시
 - **주의**: 봇이 오래된 pending을 먼저 처리하면 타이밍 불일치 발생 가능. file_permission과 run_command가 동시에 대기 시 올바른 RPC 라우팅 필수

+### [2026-03-10] active_project.lock — 멀티 프로젝트 동시 사용 차단
+- **증상**: 동일 PC에서 여러 AG 프로젝트 실행 시 첫 번째 프로젝트만 bridge 연결, 나머지는 경고 후 비활성화 시도
+- **원인**: `active_project.lock` 파일이 단일 프로젝트만 bridge 사용을 허용하는 설계. 그런데 `bridgeDisabled` 플래그 설정 후 실제로 아무것도 차단하지 않아 → 모든 인스턴스가 같은 pending/response/commands 디렉토리를 동시에 읽고 씀
+- **해결**: (1) `active_project.lock` 메커니즘 완전 제거, (2) step_probe auto-resolve scan에 `project_name` 필터 추가, (3) response watcher의 기존 project_name 필터 유지
+- **주의**: bridge 격리는 `project_name` 필드 기반 filtering으로 충분. 파일시스템 레벨 분리(옵션 B)는 불필요하게 복잡
+
+### [2026-03-10] step_probe file_permission — 3-button 미주입
+- **증상**: AG에서 파일 접근 권한 요청 시 Discord에 3개 선택지(Allow Once/Allow This Conversation/Deny) 대신 2개(승인/거부)만 표시
+- **원인**: `writePendingApproval()`이 `step_type: 'file_permission'`을 설정하지만 `buttons` 배열을 주입하지 않음. DOM observer의 `/pending` 핸들러는 `cmdLower.includes('allow')` 조건에서만 buttons 주입 → step_probe의 `view_file: /tmp/...` 형태 command에서는 trigger 안 됨
+- **해결**: `writePendingApproval()`에서 `step_type === 'file_permission'` && `!buttons`일 때 자동으로 3-button 배열 주입
+- **주의**: DOM observer 경로는 기존 command 텍스트 기반 감지 유지. step_probe 경로만 수정
