castle-search: resolve Google links lazily, in Chrome, not eagerly over plain HTTPHEADmaster

The Node-side resolver sent one curl-like request per result with no
cookies, JS or browser; Google answers that with its 'Verifying your
request' countdown after a handful, and the testing itself triggered it.
A click or direct navigation in Chrome redirects at once (measured).

Search now leaves Google links wrapped and prints the breadcrumb Google
shows for each. castle_cdp_resolve follows one wrapped link in a Chrome tab
when the agent picks it, accepts only google.com/goto?url=<token>, and
reports the verification page instead of waiting it out.
