bug: high CPU usage due to the animation and timer

Component

CLI

Summary

When using the Vibe CLI, the CPU usage is for no particular reason high when the agent is thinking. It starts okay, but as the history gets longer, the CPU usage gets higher and higher.
The culprits seem to be the animated spinner and the timer, updating 10x and 1x per second, respectively. Even though updating them almost never affects the layout, it implicitly triggers relayout all the time.

Per CONTRIBUTING.md, you do not accept code contributions at the moment. But, here's a quick fix if it helps anyone:
Branch: https://github.com/ikicic/mistral-vibe/tree/reduce_relayouts
Diff: v2.19.0...ikicic:mistral-vibe:reduce_relayouts

Possibly related to #222.

Reproduction steps

Use the CLI and monitor the CPU usage with top.

I see the issue on v2.19.1 too. Nice work with the patch!

btw, gradual output of text and text scrolling are noticeably slow and sluggish and use a lot of CPU too, even after just one query (Cost: $0.1011). It also reinvents the scrollbar instead of integrating with the terminal emulator.

The patch definitely helps but looks like the CPU use still raises while a tool permission prompt is shown.

True, I realized that in the meantime, but at first didn't want to update the branch because of this bug report. Please check again, I updated it now.
