dsh-catgirl-plugin: A token-efficient persona runtime for DeepSeek Harness

dsh-catgirl-plugin is a token-efficient persona runtime designed for DeepSeek Harness, optimized for performance through local rendering and tool pruning. Its core mechanisms include Persona Virtualization, where the model outputs standard text while the local layer injects a "catgirl" flavor, ensuring zero context pollution and zero additional LLM costs. It also features a tool whitelist control that reduces 25 tools to 8, allowing for the on-demand unlocking of missing tools via `enable_tool`. The plugin comprises modules such as `catgirl-lite`, `neko-renderer`, and `catgirl-economy`, and supports Web UI rendering. During installation, you must specify the demo profile and insert the corresponding modules and tool whitelist into the configuration.
