Fixes ethers-io#1053 Implement WebSocket reconnection and keep-alive mechanism in `WebSocketProvider`. * Add `onclose`, `onping`, and `onpong` event handlers to handle WebSocket close events and maintain connection. * Utilize the `#connect` method for reconnection purposes. * Add logic to re-establish subscriptions and pending requests on reconnection. * Include a keep-alive mechanism with ping-pong to maintain the WebSocket connection. * Modify `src.ts/providers/provider-websocket.ts` and `lib.esm/providers/provider-websocket.js` to reflect these changes. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/ethers-io/ethers.js/issues/1053?shareId=XXXX-XXXX-XXXX-XXXX).
