chore: remove stale prompts/, mayor/, and scripts/ directories

- Delete prompts/roles/*.md (duplicates of internal/templates/roles/*.md.tmpl)
- Delete mayor/rig/docs/ (stale draft, canonical version in docs/)
- Delete scripts/ (replaced by Makefile and internal/daemon/)
- Update doctor check to validate internal/templates/roles/*.md.tmpl
- Update docs/prompts.md to reflect actual template location
