Release v4.39.0

Changed

• Live Stage screen rendering now keeps table query state, row selection and binding data scoped to each table instance, including keyboard selection and selection clearing. (part of #237)
• Stage query bindings now support scoped argument rebinding and stale request cancellation before updating rendered data. (part of #237)
• Generated and live Stage frontends render through the Scene 4.9 default blueprint and PrimeReact package composition instead of flattening screen slots. (part of #236)

Fixed

• Unsupported layouts now remain visible as unresolved Scene components instead of silently substituting a default shell. (part of #236)
