feat: add docs search to the cloud provider CLIs

All three providers render their own docs search client-side, so
distilling the search page yields only nav chrome. Microsoft Learn is
the exception underneath: its public RSS search endpoint serves real
results as a feed, which the engine already renders (same route as
Stack Overflow). AWS and Google Cloud expose search only as JSON (#3),
so until the engine renders JSON their search goes through DuckDuckGo
HTML with a baked-in site: filter, the same endpoint the duckduckgo.com
CLI already relies on. Bing was tried first for that job and rejected:
it silently drops the site: operator on some queries.

Verified live: the Learn RSS endpoint returns titled results for
"app service deploy"; the DuckDuckGo route returns real
docs.aws.amazon.com pages for "lambda timeout" (it can answer with a
rate-limit challenge under rapid-fire automated use, noted in README).

Not supported yet: pages that only render with JavaScript, sites behind logins, and sites with hard bot challenges that expose no feed.
+A few of these (X, Stack Overflow, YouTube, Microsoft Learn search) read pages that look login-gated or JS-only from the outside, by finding the server-rendered HTML, feed, or inline data the page already ships without a login. AWS and Google Cloud render docs search purely client-side with no feed, so their `search` goes through DuckDuckGo with a baked-in `site:` filter instead.
