Artifact publishing always uses direct upload now; the old env var no longer exists.

What
Publishing an artifact previously took the direct-upload route only for certain entrypoints, or when CLAUDE_CODE_ARTIFACT_DIRECT_UPLOAD was set, or when a feature gate allowed it. That condition is gone and direct upload is now the only path. Neither the environment variable nor the gate name exists in this build, so setting the variable does nothing.
Evidence
CLAUDE_CODE_ARTIFACT_DIRECT_UPLOAD
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
