Cookbook/Dependencies: variant toggle now uses the agent/chat mode-toggle; Copy inside code

- Drop the 'Install via' label and the pill-tag variant buttons. The
  toggle is now the same sliding-pill mode-toggle used by the
  Agent/Chat selector in the chat input. Pip/uv on the left, Docker on
  the right, default = Pip/uv. CSS: extended .mode-chat::before's
  translateX(100%) rule to also fire on .mode-right so non-chat
  callers can use the same animation without claiming the chat-only
  class name.
- Copy button moves inside the <pre>: absolute-positioned at the
  top-right corner, icon-only, padding-right on the pre makes room.
  Matches the Setup-token copy pattern in the integrations form.
