커맨드 선택 팝업 (Ctrl+Shift+C): 커서 위치에서 빠른 명령어 전환

- command-popup: Vanilla JS 팝업 (히스토리 팝업과 동일 패턴)
  Arrow↑↓ 선택, Enter 적용, 1-5 직접 선택, ESC 닫기
- WindowManager: showCommandPopup/hideCommandPopup/sendKeyToCommandPopup
- bootstrap: Ctrl+Shift+C 단축키 등록 + command:selected IPC
- electron.vite.config: command-popup HTML 빌드 엔트리 추가
- 선택한 명령어가 즉시 activeInstructionId로 설정 → 다음 녹음에 적용
