Initialize all streamers as offline on app startup

[BP602]

Problem

When the app starts, streamers may show stale live status from previous sessions until the API calls complete. This can mislead users about who is actually live.

Expected Behavior

• All streamers should start as offline/not live on app startup
• Live status should only show as true after confirming with fresh API data

Current Behavior

• App preserves previous session's live status until API responses update it
• Can show incorrect "live" indicators temporarily

Recommended Implementation

Add this code in ChatProvider.jsx after line 803 (in the initializeOptimizedConnections function):

// Initialize all streamers as offline first to avoid showing stale live status
chatrooms.forEach(chatroom => {
  set(state => ({
    chatrooms: state.chatrooms.map(room =>
      room.id === chatroom.id 
        ? { ...room, isStreamerLive: false }
        : room
    )
  }));
});

Location

File: src/renderer/src/providers/ChatProvider.jsx
Function: initializeOptimizedConnections
After: Line 803 (after the console.log)

Acceptance Criteria

• All streamers show as offline on app startup
• Live status updates to correct state after API calls complete
• No stale live indicators from previous sessions
