Implement auto-routing for bd create (bd-ubu2)

- Add internal/routing package with DetectUserRole and DetermineTargetRepo
- Add routing config schema (mode, default, maintainer, contributor)
- Add --repo flag to bd create for explicit override
- Integrate routing logic into create command
- Test with contributor/maintainer roles and explicit override

Part of bd-8hf (Auto-routing and maintainer detection)
