Add a right-side submenu for tasks or usage

[ZachAR3]

Feature Description

The right side of the TUI is currently quite empty, so it would be nice to see a small menu there for the current todo list like opencode has or maybe a usage / pricing gauge, speed, stats, whatever. Could be user configurable.

Use Case

Would show more info to the user while not cutting off or harming the screen space that is actually being used

Additional Context

Here's an example of how it looks in opencode so you know what I'm talking about:

How important is this to you?

Nice to have

To check todos in Command Code, run /todos slash command anytime.

Yeah, but why have to run that for a plain-text output when it can be permanently in the right side which is currently empty?
