Introducing the DeepSeek Harness Token Optimization Plugin

`dsh-token-optimizer` is a plugin for DeepSeek Harness (DSH) designed to address token overhead in long sessions. It relies on hierarchical compression (L0-L2), long-text-to-image summarization, tool output routing, file diff detection, and lazy loading mechanisms to reduce consumption through incremental compression and scheduling, without re-implementing core features. As a high-privilege component, the plugin uses a fail-open strategy to maintain process availability.
