# bootstrap-deploy.sh — 编译部署 xwcode 到自举环境
# 用法: bash scripts/bootstrap-deploy.sh [TAG_OR_BRANCH]
#
# 步骤:
#   1. 在 xwcode-ar 仓库编译 release
#   2. 拷贝到自举环境 /data1/km/xwcode-xw/
#   3. 拷贝到 PATH ~/.local/bin/xwcode
#   4. 同步源码到自举环境（git pull）
#   5. 验证版本
#
# 可选指定 TAG_OR_BRANCH，自举环境会 checkout 到该版本
# 常见用法:
#   bash scripts/bootstrap-deploy.sh           # 部署当前版本
#   bash scripts/bootstrap-deploy.sh v0.85.0   # 部署指定 tag
