dsh-winget: A DeepSeek Harness Plugin for Windows Package Management

dsh-winget is a plugin that wraps the Windows Package Manager (winget) as native tools for DeepSeek Harness (DSH). It provides nine native tools supporting software search, installation, uninstallation, upgrades, manifest management, and version pinning. The plugin runs in non-interactive mode by default, making it suitable for headless environments. With simple configuration, Windows software management capabilities can be integrated into an agent, addressing the challenge of local package management for agents.
