dsh-memory-spaces: User-Autonomous Local Memory Spaces for DeepSeek Harness

`dsh-memory-spaces` is a standalone plugin for DeepSeek Harness (DSH) designed to address the difficulty of reusing decisions, constraints, and preferences across Sessions, which can be error-prone. It provides persistent, private "memory spaces" through a local SQLite database, allowing users to explicitly control which Sessions act as "sources" contributing content and which act as "consumers" reading content. Its core features include human governance, provenance, version rollback, and a pre-send review mechanism. The plugin does not rely on a global pool; all data remains fully local and requires users to manually establish connections, making it suitable for developers who need to reuse specific context across multiple conversations while prioritizing security and controllability.
