Add usage - macOS menu bar Claude Code / Codex quota monitor

[aqua5230]

Tool name: usage

URL: https://github.com/aqua5230/usage

Description: A macOS menu bar app that shows Claude Code and Codex AI quota usage at a glance. Zero API calls — reads only local status files (statusLine hook output and Codex session logs). MIT licensed, written in Python + PyObjC. Install via brew install aqua5230/tap/usage.

Thanks for maintaining this list — thought it'd fit well given the focus on AI-native/agentic coding tools!
