Add SDK features to all Ralph loop recipes

- Add WorkingDirectory/working_directory to pin sessions to project root
- Add OnPermissionRequest/on_permission_request for unattended operation
- Add tool execution event logging for visibility
- Add See Also cross-links to error-handling and persisting-sessions
- Add best practices for WorkingDirectory and permission auto-approval
- Consistent across all 4 languages (Node.js, Python, .NET, Go)
