CI 通知脚本 - 发送飞书消息通知
用法:
  NOTIFY_MODE=start JOB_NAME="Build API" python3 scripts/ci_notify.py
  NOTIFY_MODE=success JOB_NAME="Deploy Staging" python3 scripts/ci_notify.py
  NOTIFY_MODE=failure JOB_NAME="Unit Tests" python3 scripts/ci_notify.py

环境变量:
  NOTIFY_MODE     - 通知类型: start/success/failure
  JOB_NAME        - Job名称
  CI_NOTIFY_WEBHOOK - 飞书Webhook地址
  GITHUB_SHA      - Commit SHA (可选)
  GITHUB_REF_NAME - 分支名 (可选)
  GITHUB_RUN_ID   - Run ID (可选)
  GITHUB_REPOSITORY - 仓库名 (可选)
  GITHUB_SERVER_URL - Gitea地址 (可选)

设计原则:
  通知失败永远不阻断主流程（永远返回0）
