deno publish fails: adminPluginFactory default export merged with a property (TS2652) #22

deno publish --dry-run fails with TS2652: Merged declaration 'adminPluginFactory' cannot include a default export declaration. The factory is declared as export default function adminPluginFactory and then gets adminPluginFactory.pluginName = "admin"; JSR's generated type output rejects that. Introduced with the factory (0c40f61, in #17). Fix: declare the function, assign the property, then export default adminPluginFactory separately. Dry run passes with it.
