/**
 * Every computer's agent usage merged by account, for a conductor choosing
 * where to send work: `account_usage` and `phren dispatch usage`. Read like
 * `live_sessions`: this Hook, then each linked Hook over its pinned pipe, with
 * unreachable and unlinked computers listed apart.
 *
 * The merge follows the phone's cards: one account is one allowance whichever
 * computers report it, so each window comes from the newest report that has
 * it (`mergedWindows`). Claude and Codex
 * rows merge by their account key; a Claude login with no identity
 * (`claude:home:<id>`) stays per computer, since two unknown logins are not
 * one account. A window whose reset time has passed says `reset` and has no
 * percent, and a report older than STALE_AFTER_MS is flagged stale.
 *
 * `nearLimit` is information: the owner often wants quota used before it
 * resets. Only `exhausted` (a window at 100% or refusing requests) rules an
 * account out.
