# boot-public-runtime.ps1
# 목적: PC 재부팅/재로그온 후 퍼블릭 런타임을 자동으로 복구한다.
# 순서: Docker Desktop 데몬 대기 -> postgres(vignette-dev-db) 기동 ->
#       관리자/인증 API 가 이미 healthy 이고 엔진도 healthy 면 스킵, 아니면
#       start-public-runtime.ps1(-SkipWebRestart) 로 필요한 프로세스만 복구한다.
# 멱등: 어느 단계든 이미 살아있으면 건드리지 않는다. 수동으로 여러 번 실행해도 안전.
#
# 등록(로그온 시 자동 실행, 숨김 창):
#   powershell -NoProfile -ExecutionPolicy Bypass -File scripts\register-boot-task.ps1
# 또는 수동:
#   powershell -NoProfile -ExecutionPolicy Bypass -File scripts\boot-public-runtime.ps1
