DeepSeek Harness Plugin: fusion-symphony Multi-Model Fusion Orchestration Engine

`fusion-symphony` is a DeepSeek Harness (DSH) plugin designed to provide a zero-training, MoA-paradigm-based multi-model fusion orchestration solution. The plugin leverages Providers registered in DSH and defines roles such as Conductor, Worker, and Verifier through prompts to enable task decomposition, evidence ledger, deep verification, and uncompressed assembly. It supports specifying different models as Workers across Providers, offers preset modes such as fusion, hermes, and fugu, and includes capabilities such as Web search and fallback chains. Installation is performed via the Bundle mechanism; when invoking it, one must specify the list of Worker models and the preset. When using it, note that real-device verification requires restarting the GUI, and
