v0.4.4 — the counter says what it measures

The counter used to read 7 min sitting, which sounds like a claim about how long you have been at your desk. It never was: it counts agent time — the minutes an agent turn was in flight while you were present, since your last nudge. Same number, honest words, everywhere: nudge line, notification, status line, docs. The tab title now just says 🧘 time to move.
