DSH-MiMo-Agent-Tools: Integrating Xiaomi MiMo Search and Multimodal Tools into DSH

`dsh-mimo-agent-tools` is a DSH plugin designed to encapsulate Xiaomi MiMo's search and multimodal capabilities as agent tools, addressing the issues of manually handling API requests and large payload truncation. The plugin provides reasoning tools including `mimo_search`, `mimo_think`, and `mimo_json`, as well as `mimo_vision`, `mimo_audio`, and `mimo_video` that support image, audio, and video understanding, along with core features such as `mimo_asr`, `mimo_tts`, and `mimo_voiceclone` for speech synthesis, recognition, and cloning. Installation requires the DSH environment to have shell and sandboxPolicy services on the host.
