feat: support project-local workflow discovery

- Add .workflows/*.yaml scanning from project root (cwd)
- Resolution: project-local first, then global registry
- On-the-fly CAS materialization for local workflows
- Filename/name consistency check
- uwf workflow list shows origin (local/global)

Fixes #365
