docs: fix redirect loop — land on /overview, root redirects there once

Serving the landing at / via an index page loops on Mintlify hosting
(/ -> first nav page /index -> normalized back to /). Use the /overview
slug instead: / redirects there once via Mintlify's built-in behavior,
/intro and legacy intro paths redirect to /overview, no destination is
bare / anymore.
