refactor(projman): create shared visual-output skill for DRY headers

- New skill: visual-output.md defines all header, progress, and verdict formats
- All 4 agent files now reference the skill instead of inline templates
- Phase Registry table maps agents to their emoji and phase name
- Single source of truth for visual branding changes
