Today, the session config allows for configuring skills, MCP servers, etc. directly. Increasingly, people are shipping plugins that bundle multiple extension types together to accomplish a scenario. In order to avoid re-creating plugin installation support in every app, the SDK should provide a "plugin loader" that is a blessed implementation of plugin installation:

• Clones / downloads the plugin
• Unpacks to a temp directory
• Parses plugin.json and creates corresponding McpSever, SkillDirectory, etc. entries
