# 推送 NuGet 包到 Nexus nuget-hosted 仓库。
#
# 关键点：
#   1. Nexus 的 NuGet 推送认证走 HTTP Basic（账号+密码），不校验 api-key；
#   2. Nexus 为 http 源，SDK 8 需在 nuget.config 显式 allowInsecureConnections="true"；
#   3. dotnet nuget push 不支持 --configfile，只读取当前目录/用户级 nuget.config，故在此动态生成；
#   4. nuget-hosted 为 Disable redeploy（ALLOW_ONCE），重复包返回 400，
#      先调用 Nexus REST API 查重，已存在则跳过。
