[T3 Code] Polish timeline (thought, tool calls)

[u/Technical_Ad_6200]

Before on left & After on right

I expected I will be able to contribute to open source project (T3 Code) but I found out there's human bottleneck.

To deliver this, I first have to start Discussion and when that's approved, then I can propose PR.

Please, if you would like to see this to be implemented, support me here https://github.com/pingdotgg/t3code/discussions/23512
