loop/server: fix race condition in SSE stream iterators

Fix panic 'send on closed channel' when a client disconnects from SSE stream.
The issue occurred because iterators were created at the beginning of
handleSSEStream with defer iterator.Close(), but used in separate goroutines.
When the client disconnected, the iterators were closed while goroutines
were still using them.

Move iterator creation into the goroutines that use them to ensure their
lifecycle matches the goroutines' lifecycle, preventing the race condition.

Fixes #108
