Till JS 068a64b275 feat(sync): add SSE streaming endpoint for real-time sync
New endpoint GET /sync/{appId}/stream sends Server-Sent Events with
change data directly, replacing the WebSocket notification + HTTP pull
round-trip pattern.

Server (Go):
- HandleStream() in handler.go: SSE endpoint with initial sync + live streaming
- Hub.Subscribe()/Unsubscribe() in hub.go: channel-based SSE subscriber system
- Notification type for type-safe SSE events
- convertChanges() helper extracted from duplicated code
- WriteTimeout set to 0 for SSE long-lived connections

Protocol: Client connects to /sync/{appId}/stream?collections=a,b&since=...
Server sends initial changes, then streams live changes as other clients sync.
Heartbeat every 30s keeps connection alive. Push still uses POST /sync/{appId}.

WebSocket remains available as fallback (not removed).
