/**
 * @file Tests for the Artifacts hub (server/lib/artifacts.js, routes/artifacts.js):

 * file candidates and pins (a snapshot, served sandboxed), skills (snapshot,
 * symlink/secret refusal, install into the caller's Claude home with
 * replace moving the old one aside), plugins (marketplace allowlist, install
 * argv), sharing refused in local mode, visibility for a server-mode
 * developer, the admin's installs switch, and same-origin writes.
