With pr #25 we are doing
✅ Multi-platform builds - Already handled in:

• Makefile (build-all target)
• GitHub workflow (release-and-publish.yml)

✅ Version injection - Already working:

• LDFLAGS with version, commit, build date
• Embedded in binaries

✅ Release automation - GitHub Actions creates releases with:

• Binary uploads
• SHA256 checksums
• Auto-generated release notes
• npm publishing

The existing GitHub Actions + Makefile approach is clean, simple, and sufficient. we can take this issue up in future if required again
