Subject: [PATCH] Always sync full state when SSE connects

Previously only called Sync() on SSE reconnect (detected via last-event-id
header). This caused issues when application code registered contexts for
updates before the SSE connection was established - patches sent to
patchChan could be dropped.

Now always call Sync() when SSE connects, ensuring clients receive the
full current state regardless of what happened before the connection
was established.

Fixes #2
