 Gitea 저장소 등록 (웹 UI 또는 CLI)

 1) ${GITEA_URL} → New Repository
    - Name: ${REPO_NAME}
    - Owner: (조직 또는 aidev)
    - Uncheck "Initialize Repository"

 2) 로컬 개발 Mac에서:
    cd /path/to/exChatbot_agent
    git init
    git remote add origin ssh://aidev@github.exdev.co.kr:2222/aidev/${REPO_NAME}.git
    git add .
    git commit -m "Initial Agent 2.0 stack"
    git push -u origin main

 3) push 시 post-receive → deploy-exAichatbot_agent.sh 자동 실행

 서버 경로:
   GIT_DIR   = ${GIT_DIR}
   WORK_TREE = ${WORK_TREE}
   Deploy log = /Volumes/ADATA/logs/deploy/exAichatbot_agent.log

 수동 배포:
   ${DEPLOY_SCRIPT}
