Connect Gmail to Claude via mailwarden — walk the user through the one-time Google Cloud OAuth setup, `npx mailwarden --auth`, and verify with `npx mailwarden --check`. Use when the user wants to set up or repair mailwarden, when a mailwarden tool fails with "Not authorized yet", "Cannot read OAuth credentials", "invalid_grant" or "missing a Gmail scope", or when they ask how to connect a second Gmail account.
