DeepSeek Harness Interactive Learning Plugin: Native Teaching Activities and Visualization Support

The DeepSeek Harness plugin `@dsh-portable/interactive-learning` provides non-blocking instructional capabilities for agent development. Through declarative protocols and presets explicitly selected by users, it supports semantic visualization, reflective pausing, and fine-grained state management. The system uses Learn Intent to distinguish ordinary conversations from learning paths, and enables precise interaction through `dsh-learning/visual@4` and `dsh-learning/checkpoint@1`. Developers should be aware of permission risks and Session state limitations.
