Integrate Codex and Claude Code into resumable DSH sub-agents using dsh-plugin-product-subagents

`dsh-plugin-product-subagents` is a DeepSeek Harness session and messaging plugin maintained by shaokeyibb (MIT License, npm version 0.3.1). It connects ACP CLIs such as Codex, Claude Code, and Cursor/CodeBuddy/Gemini/OpenCode to the dsh sub-agent channel, providing features including resumable subtask chats, remote session recovery, a declarative role library (general/code-review/explore/debug), and delegation permission ceilings. This article verifies the installation commands, six tools and security boundaries against the community directory page, GitHub README and official sub-agent documentation.
