#57 refused absolute artifact paths at construction. Running dau-build's suite against artlink main shows that breaks 38 of its tests: dau-build's artifact model records where each output landed on the build host (bitstreams, reports, generated inputs, contributing HDL sources from other checkouts), as absolute paths, and reads them back the same way. CI did not catch it because dau-build installs the released artlink.

This keeps the containment where artlink acts on a path and drops it where artlink only carries one:

• The model refuses a path that climbs out of its manifest root with .., and accepts an absolute path as "a file on this host".
• ArtifactRegistry.artifact_file_path, build_package_archive and build_materialization_plan refuse an absolute path explicitly (before this they would have resolved outside the root, tried to pack it under the package root, or written it at an absolute destination; Fix artifact path containment and archive validation #58's resolved-path checks would have caught the last two, but with a less direct message).
• The README says so. A test carries an absolute path through the model and checks all three refusals.

This partly reverses one line of the readiness decision; the alternative, moving dau-build and its consumers to manifest-relative paths plus file: URIs for external provenance, is a multi-repository change that the containment the registry and materializer already enforce does not justify.
