v1.1.1

• SSE now survives non-200 responses (qfg-41nh.9). The SDK owns SSE reconnection instead of
  delegating it to the eventsource package, which treats any non-200 response as terminal — a
  single 502 from the edge during a deploy used to kill real-time updates for the process lifetime
  (silently degrading to the 60s fallback poll). Every SSE failure now tears down and recreates the
  connection with jittered exponential backoff (500ms doubling to a 30s cap, retrying forever),
  matching sdk-go. This also replaces the previous constant ~3s reconnect delay on network failures.
  The stream stays pinned to the primary stream URL; there is no rotation.
• Immediate fetch when the fallback poller engages after SSE loss (qfg-41nh.9). When the Layer 2
  HTTP poller engages after the 120s disconnect grace window, it now fetches immediately instead of
  waiting a further full poll interval — first data after SSE loss arrives at ~120s (matching
  sdk-go/java/net) instead of ~180s.
