-- **Duplicate Rake Task Execution**: Fixed rake tasks executing twice during asset precompilation and other rake operations. Rails Engine was loading task files twice: once via explicit `load` calls in the `rake_tasks` block (Railtie layer) and once via automatic file loading from `lib/tasks/` (Engine layer). This caused `react_on_rails:assets:webpack`, `react_on_rails:generate_packs`, and `react_on_rails:locale` tasks to run twice, significantly increasing build times. Removed explicit `load` calls and now rely on Rails Engine's standard auto-loading behavior.

 - **Node Renderer Worker Restart**: Fixed "descriptor closed" error that occurred when the node renderer restarts while handling an in-progress request (especially streaming requests). Workers now perform graceful shutdowns: they disconnect from the cluster to stop receiving new requests, wait for active requests to complete, then shut down cleanly. A configurable `gracefulWorkerRestartTimeout` ensures workers are forcibly killed if they don't shut down in time.

 - **Body Duplication Bug On Streaming**: Fixed a bug that happens while streaming if the node renderer connection closed after streaming some chunks to the client. [PR #1995](https://github.com/shakacode/react_on_rails/pull/1995) by [AbanoubGhadban](https://github.com/AbanoubGhadban).
