feat(FN-3883): fix dependency-graph plugin exports and add CLI bundle entry

Fixed the `@fusion-plugin/dependency-graph` plugin's exports and build entry points so it bundles correctly with the CLI, added test coverage for plugin enable success and error-state toasts, and included the plugin's dist in the CLI bundle via tsup config.

+Fix Dependency Graph plugin failing to enable from Settings by correcting package exports/build output and ensuring bundled CLI staging includes compiled plugin dist assets. Also surface the loader's actual enable error in Plugin Manager toast messaging when enable returns `state: "error"`.
