Previously, opening an agent screen would skip fetching timeline history
if stream state already existed in the cache. This caused issues when:
- Opening a running agent after reconnection
- Returning to an agent with stale/incomplete cache
Now we always fetch fresh timeline on open, ensuring:
- Complete history is shown regardless of client state
- Reconnection scenarios work correctly
- Agent state is always up-to-date
Uses a ref to track initialization per mount to prevent infinite loops.
