Rolled back binary updater replacements when post-install version verification fails instead of deleting the previous working binary first.
Added a release workflow gate that downloads the published macOS arm64 asset and verifies codesign plus --version before npm publishing.
Fixes#1240
- Removed export leakage by demoting many helper and const symbols to module-local scope.
- Renamed underscore-prefixed internals and cache fields, then updated related references and `satisfies never` checks.
- Deleted obsolete logic branches and helpers, including harmony-stream interruption flow and unused benchmark runtime helpers.
- Updated Biome config and manifests by broadening lint coverage and removing an unused `@napi-rs/cli` dev dependency.
- Adjusted tests and utilities to use renamed test helpers and remove redundant private test-only helpers/locals.
