i-am-yuike: Catgirl Yuike Character Plugin

The i-am-yuike plugin is designed specifically for DeepSeek Harness (DSH) to enable the persona to fully take over the system prompt, remove redundant framework information, and deliver a pure role-playing experience. It is configured to ensure that the persona drives the identity and style, and it disables toolchains such as `skill-filesystem` and `tool-skill` to keep the conversation clean while retaining core development capabilities. After installation, select the `yuike` preset to enable it. Usage note: to prevent persona collapse, it is recommended to run one non-thinking conversation turn before enabling thinking mode in order to establish context. The plugin supports DSH 0.1.6 and later, and the source code is available on GitHub.
