dsh-s2s — DeepSeek Harness Same-Host Session Interconnection Plugin

`dsh-s2s` is a lightweight plugin for DeepSeek Harness designed to address collaboration among multiple AI Agent sessions on the same host. It eliminates cross-host network communication and uses an in-process Broker for zero-port, zero-reconnection direct message delivery. The plugin supports in-process delivery, Name-based primary addressing, resuming dormant sessions, and loop-prevention rate limiting. It provides six core tools for session management, message sending, and history queries, and supports persistent message storage. During installation, configure `autoResume` and `budget` to enable automatic session resumption and rate limiting, making it suitable for low-complexity scenarios requiring only same-host collaboration.
