"""
|

Windows / macOS 本地开发：SSH 隧道把线上 MinIO/PocketBase 映射到本机。
|
||
|
||
默认映射：
|
||
localhost:9100 -> 服务器 127.0.0.1:9100 (MinIO S3 API)
|
||
localhost:8090 -> 服务器 127.0.0.1:8090 (PocketBase，可选)
|
||
|
||
用法：
|
||
python scripts/dev-tunnel.py
|
||
|
||
环境变量（推荐写在 cursor.env，也可写在 .env.local）：
|
||
DEV_SSH_HOST=82.157.112.245
|
||
DEV_SSH_USER=ubuntu
|
||
DEV_SSH_PASSWORD=你的密码
|
||
DEV_TUNNEL_MINIO_PORT=9100
|
||
DEV_TUNNEL_POCKETBASE=0 # 设为 1 时同时映射 8090
