`dsh-market-desktop`: DSH Desktop Visual Plugin Marketplace

The DSH desktop plugin marketplace provides users with a visual plugin management interface, replacing command-line operations and lowering the installation barrier. It supports browsing, searching, and one-click installation of community plugins, and includes the ability to fix dependency errors, automatically rewrite outdated dependencies, and guide pnpm configuration. The installation command is `dsh plugin --profile desktop add github:KokuYu-sysu/dsh-market-desktop`. Users should note the package name distinction; if a pnpm version restriction is encountered during installation, they must allow build scripts and independently assess plugin permissions and security.
