A plugin's update diff now includes its marketplace.json entry as a pretty-printed "marketplace.json entry" file, so inline hooks, MCP servers and commands are reviewed like any file. CatalogItem gains plugin_components (entry / plugin.json runnable keys, hooks/hooks.json, .mcp.json, commands/), and installing a plugin now goes through PluginConfirmModal listing them. The import-preview warnings describe that confirmation accurately. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
