dsh-model-visibility: DeepSeek Harness Model Selector Filter Plugin

dsh-model-visibility is a plugin for DeepSeek Harness designed to address overly long model selection menus. It supports real-time filtering by model name, ID, or channel name, and allows toggling model visibility individually or in bulk for an entire provider. The plugin does not modify provider configurations; it only maintains its own hidden list, and hiding models does not interrupt the current session. It features coordination between the browser side and host side, supports one-click restoration, and automatically cleans up upon uninstallation. Compatible version: DSH ≥ 0.2.0-rc.1.
