Pages for startups and for teams

Two new pages answer "is this for us?" with the setup, not a pitch.

• QA for startups. One test in plain English, the GitHub App on every pull request, the ZeusQA check made required, and schedules on Pro for the flows that make money. What Free, Pro and Team give a small team, and what they do not.
• QA for engineering teams. One workspace across many repositories: when each one runs, what it tests, whether it blocks the merge, who can change it, and the run budget the whole team shares on Team.
• The limits, stated. No single sign-on, no independent audit, GitHub only, email alerts only and schedules at most hourly, on the page rather than after signup.

The plan numbers on both pages are read from the same place as the pricing page, so they change together.
