feat: Improve CLI (#5)

* Start working on improved CLI

* Add tool result previews, boxed approval card, and polished help screen

REPL iteration 2: styled /help with grouped sections, box-drawing
approval card with colored params, dim separator before responses,
inline tool output previews via new StatusUpdate::ToolResult variant.
