Related to #26819.
An optional timeout parameter has been added to the Deno.connect() interface. This parameter allows specifying a timeout (in milliseconds) within which the application must establish a connection. If the timeout is exceeded without successfully connecting, the operation is automatically aborted with an error. If the parameter is not provided, the default behavior remains unchanged (no timeout).
Currently, the timeout functionality is implemented only for TCP connections. Other connection types are not affected by this change.

Example usage:

try {
  const conn = await Deno.connect({
    hostname: "example.com",
    port: 5000,
    timeout: 5000, // 5 second timeout
  });

  console.log("Connection established successfully");  
  conn.close();
} catch (error) {
  if (error instanceof Deno.errors.TimedOut) {
    console.error("Connection timed out:", error.message);
  } else {
    console.error("Failed to connect:", error.message);
  }
}

If this solution is approved, the documentation will need to be updated to include details about the new timeout parameter.
