DeepSeek Harness Plugin: rangeking/dsh-iris Progressive Capability Routing

`rangeking/dsh-iris` is a plugin designed for DeepSeek Harness to address the context bloat and selection confusion that agents face when working with large tool sets. Through a progressive capability routing mechanism, it allows models to select capabilities on demand based on descriptions, thereby optimizing resource usage. The plugin supports adaptive mode, MCP interfaces, and retention of native character roles. After installation, developers can configure card budgets and use the `iris_activate` and `iris_search` interfaces to precisely manage capability loading. In terms of permissions and runtime boundaries, it ensures safe metadata reading and proper attribution of native descriptions, providing agents with fine-grained and secure control over tool invocation.
