ci: release 后调 Bark 推送 release 通知

release job 在 softprops/action-gh-release@v2 上传完
spark-mcp-linux-amd64 后, 调 Bark (http://101.43.40.124:81/push) 推
一条 device_key 绑定的通知, 标题用 github.ref_name (e.g.
v0.0.1-beta), body 带 release 页面 URL.

device_key 直接写进 workflow, 是公开的推送 key, group=backup
归档, ttl=3600 (1 小时后从 Bark 设备上消失).

if: success() 保证 release upload 失败时不会发通知, 避免推送
"已发布" 但实际没有的误导信息.
