Fix OpenClaw dialogue command execution exits in Alpine image

[Copilot]

在当前镜像中，OpenClaw 进入对话后，一旦触发命令执行路径会出现进程退出。问题集中在容器运行时依赖不完整，而非对话逻辑本身。

• Runtime dependency alignment (Alpine)

  • 在 Dockerfile 中为运行镜像补充 bash，以满足 OpenClaw 命令执行链路对 shell 的依赖。
  • 保持现有启动方式不变（未调整 onboard --install-daemon 入口行为），仅修复执行期依赖缺口。

• Minimal change scope

  • 仅改动 Docker 运行层安装包列表，避免影响现有配置与启动流程。

RUN apk add --no-cache bash ca-certificates libssl3

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• docs.openclaw.ai
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
