Version Update:
- Bumped workspace version from 0.15.0 to 0.16.0
- Updated all plugin dependencies to 0.16.0

Docker Build Improvements:
- **Commented out full release-docker target**: Temporarily disabled complete Docker build
- **Enabled latest tag publishing**: Uncommented latest tag pushes for both architectures:
  - `latest-amd64` and `latest-arm64` for individual architectures
  - Multi-arch `latest` tag creation in merge target

Key Changes:
1. **Version Increment**: Major version bump to 0.16.0 for all components
2. **Docker Pipeline**:
   - Disabled full release-docker to focus on per-architecture builds
   - Enabled latest tag publishing for better deployment flexibility
   - Maintained multi-arch manifest creation for latest tag

3. **Consistency**: All workspace dependencies synchronized to 0.16.0

Benefits:
- **Clear Version Progression**: Proper semantic versioning with major release
- **Improved Docker Deployment**: More flexible tagging strategy
- **Multi-arch Support**: Enabled latest tags for both AMD64 and ARM64
- **Maintenance Friendly**: Commented code preserved for future reference

This prepares the codebase for the 0.16.0 release with an improved Docker build and publishing workflow.
