OpenCode Go signs in too, every account
OpenCode Go connects through the same OpenCode sign-in as Zen, extra Go accounts sign in without a key, and Go usage still shows.
One sign-in for both plans
OpenCode now signs accounts in instead of handing out keys, and one sign-in pays for Go as well as Zen. The Go tile has Sign in with OpenCode, and on the OpenCode card, Sign in another Go account adds a second Go account the same way. Each account shows the email it signed in with and keeps its own sign-in.
Requests now name the organisation you signed in with the way OpenCode reads it, so they bill to the right workspace. Your Go usage bars keep working after a sign-in, and you can still paste a Go key if you prefer one.
