Prerelease Alpha 31 — Browser tabs with agent cockpits

The browser becomes a real workspace. Alpha 31 introduces browser chrome with an agent cockpit per tab, so each browsing task can keep its own context instead of collapsing back into one shared lane.

The session timeline reads better. Tool-call cards were redesigned to separate inputs from outputs more clearly. This is the kind of change that makes long sessions survivable; you stop scanning walls of mixed state and start seeing what the agent actually did.

Accounts and scheduling got sharper. Lark, Box, and Dropbox appear as connect tiles. Google Drive gets a scope toggle. Microsoft account selection now uses an account-picker prompt. The scheduler adds an hourly pattern. Under the hood, all vendor OAuth callbacks moved to one-time code exchange, so tokens no longer ride back in callback URLs.
