Artifact reads can bind a local file as a synced working copy, with refusals when a copy is already bound.

read_file/read actions for artifacts can now bind a local file to a live artifact document as a synced "working copy." New logic resolves liveFileCopyPathForRead, checks workingCopyLocationRefusal, and can refuse to overwrite an existing bound copy via snapshotOntoWorkingCopyRefusal. Read results can now include a working_copy field and a seq value.
