The server's ReadTimeout (15s) was closing SSE connections shortly after they were established, causing a rapid connect/disconnect loop:

SSE reconnecting (1/10): connection closed
SSE connected
SSE reconnecting (2/10): connection closed
SSE connected
...

The handler already disabled WriteTimeout via SetWriteDeadline(time.Time{}) but did not disable ReadTimeout. Once the read deadline fired, Go's HTTP server closed the underlying connection.

Fix: Also call rc.SetReadDeadline(time.Time{}) to keep the connection alive indefinitely.

The server's `ReadTimeout` (15s) was closing SSE connections shortly after they were established, causing a rapid connect/disconnect loop: ``` SSE reconnecting (1/10): connection closed SSE connected SSE reconnecting (2/10): connection closed SSE connected ... ``` The handler already disabled `WriteTimeout` via `SetWriteDeadline(time.Time{})` but did not disable `ReadTimeout`.
