Subject: [PATCH 1/2] Add WinUI plugin from microsoft/win-dev-skills

Adds the winui plugin entry, pointing at the released v0.6.1 tag and
its portable Agent Plugins package (plugins/winui/agent-plugin) in
microsoft/win-dev-skills. Follows the same external-plugin pattern
already used for workiq, azure-devops-copilot-plugin, fabric-skills,
and power-platform-skills.
