Add usage — macOS menu bar quota monitor for Claude Code and Codex

[aqua5230]

Adds usage to the Tools list (alphabetical order, between Unblocked and v0.dev).

• Pins Claude Code and Codex quota (5-hour / weekly) to the macOS menu bar, with burn-rate predictions and offline HTML usage reports
• Never calls the Anthropic/OpenAI API; reads only local files, so monitoring adds zero token overhead
• Free, open source (AGPL-3.0), installable via brew install --cask aqua5230/usage/usage

Thanks for the submission. The project qualifies, but the description is outdated. It now supports Windows and Antigravity, and Antigravity uses network APIs, so “reading only local files” is too broad.

Suggested replacement:

usage - A macOS menu-bar and Windows system-tray app for monitoring Claude Code, Codex, and Antigravity quotas, with burn-rate estimates and locally generated usage reports.

Thanks for the review — you were right, the description had gone stale. I've pushed an update to this PR using your suggested wording:

usage - A macOS menu bar and Windows system tray app that monitors Claude Code, Codex, and Antigravity quota, with burn rate estimates and locally generated usage reports.

Your point about "reads local files only" being too broad was well taken. Antigravity quota genuinely does come over the network from Google's quota endpoint, so the old blanket claim was wrong. I've corrected the same overreach in the project's own README, SECURITY.md, and landing page — SECURITY.md now lists every outbound request the app makes, rather than claiming there are none.
