Description

Unfortunately, the previous publish was not working for the new targets as of course, OIDC publishing requires some extra steps... Hopefully this works now.

Pull request overview

This PR fixes the OpenBSD package naming to ensure OIDC publishing works correctly. The original package name included a specific OpenBSD version (7.8) which was causing issues with the OIDC publishing workflow.

Key changes:

• Rename OpenBSD package from @rollup/rollup-openbsd7.8-x64 to @rollup/rollup-openbsd-x64 to follow the platform naming convention
• Update version to 4.55.1-0 (pre-release) across main packages
• Update native.js binding reference to use the corrected package name
