Add Headroom — native macOS Claude Code usage monitor

[Pat Walls (patwalls)]

Headroom is a free native macOS menu bar app that monitors Claude Code's session (5h) and weekly (7d) usage limits as a live percentage in the menu bar.

Why Developer Productivity section:

• Lives in the macOS menu bar — zero UI friction, always visible
• Color-coded: green → amber at 80% → red at 90%
• Shows session cost, active model, context window fill, reset countdowns
• Zero network calls — reads a local file written by Claude Code's own status line hook (no API keys, no polling)
• Native Swift, MIT license, signed & notarized, ~267 KB, macOS 13+
