fix: feat: RESOURCES.md — infrastructure manifest for planner resource awareness (#23)

- Add RESOURCES.example.md: committed template showing Compute/Domains/Accounts/Budget structure
- Gitignore RESOURCES.md so local infrastructure data is never committed
- Planner phase 2 reads RESOURCES.md from factory root when present
- Planner prompt instructs Claude to reference specific resource aliases in operational issues
