Intel and Apple Silicon macOS jobs produced the same updater bundle filename,
which let one matrix job overwrite the other release asset and could point
both architecture manifests to a single binary. Rename macOS updater bundles
per architecture before release upload and prefer arch-specific artifact lookup
when generating updater manifests.
Constraint: Keep existing updater manifest format and release action usage
Rejected: Split macOS uploads into separate release jobs | larger workflow churn
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Any new macOS updater lane must keep unique asset names to preserve manifest correctness
Tested: release-tauri.yml YAML parse; diff audit for rename+manifest path alignment
Not-tested: End-to-end tagged GitHub Actions release run
