[Bug] CLI input lag in extended sessions with high context utilization

Bug Description
Performance issue: CLI input lag after extended sessions

• After ~30+ interactions in the same context window, typing becomes very slow with noticeable delay
• Context usage at time of issue: ~64% (128k/200k tokens)
• The lag is in the input field itself, not in response generation
• Workaround: starting a new session resolves the issue
• OS: Linux 6.1.0-40-amd64

Environment Info

• Platform: linux
• Terminal: gnome-terminal
• Version: 2.0.72
• Feedback ID: de37b920-12f5-49c3-b5e7-404a21ab0902
