dsh-remote-subagent: Dispatching tasks from local session to remote machine's DSH subagent

`dsh-remote-subagent` is a DSH workflow plugin maintained by `deepseekv41flash` (v0.1.0, MIT). It enables local sessions to invoke the remote `dsh headless --json` via SSH using the `remote_agent` tool, reading back `thinking`, `tool_call`, `tool_result`, and `final` event streams in real-time. It also allows using `send` to ask follow-up questions within the same remote session. The remote side utilizes its own model configuration, tools, and sandbox without the need to open public network ports. The article introduces installation commands, the seven `remote_agent` actions and their reuse semantics, the panel data interface, optional configurations, typical call sequences, real-world test status, and known limitations (e.g., only supporting POSIX remote environments).
