dsh-whale-market: Browse, Install and Update DSH Community Plugins

dsh-whale-market is a community-maintained DSH plugin marketplace that provides a unified entry point for browsing, searching, installing, and updating DSH plugins on GitHub. It operates within the DSH Web settings page and integrates four agent tools: market_search, market_install, market_installed, and market_update. Core functions include real-time market browsing (supporting plugins, Skills, skins, and presets), multi-dimensional search filtering (categories, languages, sorting, etc.), and automatic Chinese keyword expansion. The system features a four-level data degradation mechanism, enabling continued service via static indexes or built-in seeds under poor network conditions. The installation process includes type detection, compatibility scoring, and a risk confirmation gate, supporting multiple installation formats and incorporating error fallback.
