    Interface FetchPlugin<H, P, S>

    Plugin contract for extending FetchEngine with hook-based behavior.

    Plugins wrap existing functionality (cache, dedupe, rate-limit) or add new capabilities by registering hooks on the engine. Each plugin returns an unsubscribe function from install() for cleanup.

    function authPlugin(getToken: () => Promise<string>) {
            return {
                name: 'auth',
                install(engine) {
                    return engine.hooks.add('beforeRequest', async (url, opts, ctx) => {
                        const token = await getToken();
                        ctx.args(url, { ...opts, headers: { ...opts.headers, Authorization: `Bearer ${token}` } });
                    });
                }
            } satisfies FetchPlugin;
        }
    interface FetchPlugin<H = unknown, P = unknown, S = unknown> {
        hooks?: HookEngine<any, [string]>;
        name: string;
        install(engine: FetchEnginePublic<H, P, S>): () => void;
