"""Shared-runtime behaviour tests for the WebSearch ``visit_web`` tool.
The plugin declares an empty ``spec.config``, so the two-binding test proves the
shared component object derives every invocation purely from its arguments and
retains no per-tenant state across bindings. The remaining tests cover the
blocking ``mux.process`` call (site adapters use the synchronous ``requests``
library) and the previous shared-default list in ``SiteAdapterBase.make_ret``.
