Introducing the DeepSeek Harness Plugin: dsh-engram-session

`dsh-engram-session` is a standalone plugin for DeepSeek Harness (DSH), designed to address the persistence and isolation of agent session memory. It instantiates an independent Engram MCP subprocess for each session and uses deterministic root directory resolution and scope isolation to ensure stable memory storage without tool conflicts. The plugin features a zero-side-effect design, easy removal, and reuse across configurations. Note that it is unofficial, lacks a subprocess reconnection mechanism, and supports only text result projection.
