chore: rename uwf-* → workflow-*, cli-uwf → cli-workflow

Reclaim the workflow-* package names now that legacy packages are archived.

Package renames:
- @uncaged/uwf-protocol → @uncaged/workflow-protocol
- @uncaged/uwf-moderator → @uncaged/workflow-moderator
- @uncaged/uwf-agent-kit → @uncaged/workflow-agent-kit
- @uncaged/uwf-agent-hermes → @uncaged/workflow-agent-hermes
- @uncaged/cli-uwf → @uncaged/cli-workflow

All internal imports, tsconfig references, and docs updated.
CLI binary name 'uwf' unchanged.
