/**
 * @file Tests for the Artifacts hub (server/lib/artifacts.js, routes/artifacts.js):
 * claude.ai pages (link allowlist, hook capture, one row per URL), workspace
 * 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; a marketplace link read into its plugin list, the same plugin added
 * twice kept as one row, key/market edited), skills uploaded (one Markdown
 * file, a folder, a zip, several skills at once — name and frontmatter set,
 * junk skipped, nothing stored when one fails) or written in the dialog, a
 * file uploaded, sharing refused in local mode, visibility for a server-mode
 * developer, the admin's installs switch, and same-origin writes.
