ArtifactsJs: wrapper that gives scripts a dedicated write-scoped
directory for outputs like screenshots, PDFs, traces, downloaded bodies.
Separate from fs (which is rooted at script_root and is primarily
for reading fixtures + importing modules). artifacts is rooted at
artifacts_root and is primarily for writing — keeps outputs out of
your source tree.
Same sandbox rules as fs: absolute paths, .., and symlink escapes
are rejected. Names are resolved relative to the artifacts root.
