refactor: consolidate publishing into unified system

- Create comprehensive PUBLISHING.md guide replacing scattered docs
- Replace old workflows with unified manual-only publish.yml workflow
- Add container.yml for manual container publishing
- Consolidate scripts into scripts/ directory
- Add architecture selection and registry options
- Remove automatic triggers, make all publishing manual
- Fix gofmt hints in OpenShift AI toolsets

Features:
- Manual-only publishing with workflow dispatch
- Architecture selection for targeted publishing
- Unified documentation for all publishing methods
- Clean separation of GitHub Packages vs public npm
- Container publishing with multi-architecture support
