deploy write / build-and-deploy (push) Failing after 4s
- 整 apps/write/ 进 git（含 frontend 源码 + Makefile + systemd unit + k8s service/ingress）
- .gitea/workflows/deploy-write.yml: act_runner fam 用户跑 host shell
cargo build → npm build → install 到 ~/.local/bin/share/config →
systemctl --user daemon-reload + restart → kubectl apply svc/ingress
- 前端 3 处"麻薯"字样去掉（思考中 / placeholder × 2）
注意 ~/.config/write/env 已有 passphrase，CI placeholder 逻辑会跳过不覆盖。
