Pin SearXNG for Google, drop DuckDuckGo

The May image's GSA Google parser returns empty JS shells. Pin a
2026-08-29 digest with the Nokia/WML parser, keep Bing, and omit
DuckDuckGo because it CAPTCHAs this host. Document the explicit
SearXNG recreate because start never replaces containers.

+Google is a scraper. A successful HTTP 200 with zero results usually means
