Legend Chat History 0.0.2

• Perf: Launches faster by showing the restored window and sidebar immediately while loading the last selected chat before React Native starts.
• Perf: Large transcripts and chat switches render more smoothly through faster Codex parsing, reusable list state, and correctly sized images that avoid layout shifts.
• Fix: Reopening the app now refreshes chats without creating duplicate windows, restores the saved window frame, and keeps sidebar content correctly aligned beneath the transparent titlebar.
