- Move 15 old workflow-* packages to legacy-packages/ (inactive, preserved for reference)
- Rename templates/ → examples/ for clarity
- Rewrite docs/architecture.md to reflect current uwf architecture
- Active packages remain in packages/: cli-uwf, uwf-agent-hermes, uwf-agent-kit, uwf-moderator, uwf-protocol, workflow-util
