[FEATURE] Provide consistent token usage status

Problem Statement

I often have separate terminals open to monitor different things. Occasionally, since I'm on a limited token plan, I'll check my token usage via the Claude CLI's /usage. However, this only provides a snapshot of the current token usage and does not update in real time.

Proposed Solution

I'd like to be able to have a separate terminal instance running the Claude CLI where I input /usage<updates> or similar so that I can have a terminal consistently displaying real time usage status.
