Run the deterministic release script:
pnpm release:desktop [x.y.z]
Omit the version to increment the patch version. Use --dry-run to preview or
--yes to skip confirmation.
The script requires a clean, synced main; validates and promotes Unreleased;
runs pnpm build:desktop; shows the release diff; commits; tags; and atomically
pushes main with desktop-vx.y.z. GitHub Actions publishes the release.
