Add example Claude desktop config

Add data/claude_desktop_config.example.json providing an example desktop configuration for the Claude app. It defines an "mcpServers" entry ("local-tools") that invokes Windows cscript to run app.js with mcploader args, and a "preferences" block with toggles for cowork/ccd scheduled tasks, cowork web search enabled, and sidebarMode set to "chat".
