dsh-memory-hermes: Hermes-Style Bounded Planning Memory Plugin

`dsh-memory-hermes` is the memory plugin for DeepSeek Harness, designed to address the issue of agent memory bloat. It provides a “bounded curated memory” solution, maintaining refined `MEMORY.md` and `USER.md` files and improving prompt-cache friendliness through frozen snapshots and background introspection mechanisms. The plugin offers core features such as dual-file memory, skill-library consolidation, security scanning, and concurrency safety. With simple configuration and hot-reload support, it effectively manages context and prevents overflow, making it suitable for development scenarios requiring long-term stable state and knowledge accumulation.
