bug: transport/streamable_http.go context timeout on sse stream

[gosthell]

Description

There is a timeout set on the context of the sse stream of streamable_http.go, this leads to the stream timing out every 10 seconds

Code Sample

func (c *StreamableHTTP) listenForever(ctx context.Context) {
	c.logger.Infof("listening to server forever")
	for {
		// Add timeout for individual connection attempts
		connectCtx, cancel := context.WithTimeout(ctx, 10*time.Second)
		err := c.createGETConnectionToServer(connectCtx)
		cancel()

Logs or Error Messages

2025/08/19 21:05:26 ERROR: failed to listen to server. retry in 1 second: failed to handle SSE response: context deadline exceeded

Environment

n/a

Additional Context

I feel like that logic was copied from the SSE transport for which timeout made sense since we were waiting from a response json rpc from the server, but here the SSE is only for receiving requests / notifications and not response

Possible Solution

Remove the timeout, or reset the timeout on new messages, relying on heart beat from server
