Align release artifacts with the published platform matrix

Constraint: Local Apple Silicon Docker/Wine builds are not stable for Windows packaging
Rejected: Keep auto-bumping build versions at packaging time | website and artifact versions drifted
Confidence: medium
Scope-risk: moderate
Directive: Keep package.json, generated download links, and packaged artifact versions identical for every public release
Tested: typecheck, lint, workspace typecheck, unit tests, integration tests, e2e smoke locally
Not-tested: GitHub-hosted Windows/Linux runner outputs before workflow execution
