Closes #19, #20, #21, #27. #19 — a saved auth profile now reports how much of its account's quota is already spent, which is the only number that decides which one is worth switching to. Nothing under CLAUDE_HOME records it, so it comes from the same endpoint the CLI's own /usage reads, answered for whichever account's OAuth token is presented. It is a POST and a button, never a poll: every profile that is not the active one is normally expired, so answering means refreshing it first, and a refresh ROTATES the stored refresh token. The rotated pair is written straight back — dropping it would leave the profile holding a credential Anthropic has already retired, i.e. an account needing a fresh login. The token is read, put in an Authorization header, and never returned, logged or echoed; what leaves the server is two percentages and two reset times. #20 — a settings patch that changes nothing wrote nothing but still took a timestamped backup, so opening the config panel quietly grew a backup directory inside every lane. patchSettings now compares the rendered output with what is already on disk and returns early, fixed once where all callers route through. A lane's git exclude also picks up .claude/.cc-config-backups/ beside settings.local.json. #21 — the router apply route was the only mutating lane route that never broadcast its lane. The write reached disk and the column, but the client's cached row kept the old router_profile forever: the picker looked right until the user switched lanes and back, at which point the effect re-read the stale row and flipped the selection to the previous profile. One broadcastLane, plus a lane-switch guard so an apply that resolves after the user has moved on no longer paints its result onto whichever lane is now on screen. #27 — Add-lane in worktree mode left the dialog up after a clean setup with a dead confirm button and no obvious way out. It closes itself when nothing failed, and when something did, the summary stays and the confirm becomes a real Close.
