Package release 0.4.167 from the current workspace snapshot

Constraint: Windows and Linux artifacts are built on native GitHub runners from a temporary snapshot branch
Rejected: Build Windows/Linux locally on Apple Silicon | docker/wine packaging is not stable on this host
Confidence: medium
Scope-risk: moderate
Directive: This snapshot branch is transport-only and should be deleted after the release completes
Tested: local verify/build stages before snapshot creation
Not-tested: remote packaging before workflow execution
