Install a package from the Unity Package Manager registry, Git URL, or local path. This operation modifies the project's manifest.json and triggers package resolution. Note: Package installation may trigger a domain reload. The result will be sent after the reload completes. Use 'package-search' tool to search for packages and 'package-list' to list installed packages.
