Reviewer's GuideThis PR refactors DefaultTcpSocketClient by streamlining the ConnectAsync workflow (early endpoint assignment, conditional auto-receive, return-value logic), simplifying connection checks in ReceiveAsync, and correcting the buffer-length assignment in ReceiveCoreAsync.

Pull Request Overview
This PR refactors the ITcpSocketClient connection and data receiving logic to optimize code structure and improve clarity in endpoint management and asynchronous operations.
- Moves remote endpoint assignment before initiating connection.
- Utilizes pattern matching for client connection checking.
- Adjusts buffer length handling and background task invocation for auto-receive.

- Assigning 'len' directly to 'buffer.Length' may not reflect the actual number of bytes received by DataPackageHandler.ReceiveAsync. Please verify that this assignment is correct and aligns with the intended packet handling logic.
len = buffer.Length;

Hey @ArgoZhang - I've reviewed your changes - here's some feedback:
- Consider moving the
_remoteEndPoint = endPointassignment to after you’ve verified the connection succeeded so you don’t store an endpoint on failed connects. - In
ReceiveCoreAsync, settinglen = buffer.Lengthmay not reflect the actual bytes received—use the actual count returned by the receive call instead of the buffer’s capacity. - When you fire off
AutoReceiveAsyncwithTask.Run, wrap it in a try/catch or attach a continuation to log exceptions so you don’t end up with unobserved task faults.

## Overall Comments
- Consider moving the `_remoteEndPoint = endPoint` assignment to after you’ve verified the connection succeeded so you don’t store an endpoint on failed connects.
- In `ReceiveCoreAsync`, setting `len = buffer.Length` may not reflect the actual bytes received—use the actual count returned by the receive call instead of the buffer’s capacity.
- When you fire off `AutoReceiveAsync` with `Task.Run`, wrap it in a try/catch or attach a continuation to log exceptions so you don’t end up with unobserved task faults.

// 创建新的 TcpClient 实例
_client ??= new TcpClient(localEndPoint);
+ _remoteEndPoint = endPoint;
var connectionToken = token;
</code_context>
<issue_to_address>
Assigning _remoteEndPoint before connection may not reflect the actual remote endpoint.
Assign _remoteEndPoint after confirming a successful connection to ensure it accurately reflects the connected endpoint.
