The release workflow only produced Apple Silicon macOS packages, so Intel
users had no official GitHub Release artifact. Extend the matrix with an
x86_64 macOS lane and align artifact naming and updater-manifest paths
with per-arch outputs.
Constraint: Keep existing release pipeline shape and signing flow unchanged
Rejected: Split Intel build into separate workflow file | higher maintenance and duplicated logic
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep macOS conditions architecture-agnostic so new mac runners are not skipped accidentally
Tested: YAML syntax parse via python yaml.safe_load; workflow diff reviewed for mac gating/artifact paths
Not-tested: Full GitHub Actions matrix run on tag push
