dsh-auto-continue: Automatically send "continue" after interruption in DSH Web UI

dsh-auto-continue is a workflow plugin for the DSH Web UI, maintained by HsiangNianian. When a session is interrupted due to non-human reasons such as network errors, timeouts, or max-tokens, it automatically sends a configurable "continue" text via agent.followup to resume the task. The engine has been running within the host process since version 0.8.0, supporting error classification, adaptive backoff, idempotent safeguards, loop guards, pause functionality, and a statistics panel. Installation: dsh plugin --profile web add dsh-client-auto-continue, requiring DSH ≥ 0.1.0-rc.7.
