URL: https://github.com/apache/hop/issues/6541

   ### What would you like to happen?
   
   In Apache Hop, when multiple transforms are selected inside a Pipeline, the 
user should be able to right-click the selection (or any selected transform) 
and see a new context-menu action: “Create Sub-Pipeline” or “Create Mapping”.
   When triggered, the system encapsulates the selected transforms into a new 
artifact and replaces the selection with a single step referencing that new 
artifact.
   
   Key functional requirements:
   
   Visible only when 2+ transforms are selected.
   
   Create a new sub-pipeline/mapping containing the selected transforms and 
internal hops.
   
   Auto-rewire external inputs/outputs to the new reference step.
   
   Preserve transform configuration and metadata.
   
   Provide a minimal dialog for:
   
   artifact name,
   
   save location,
   
   “open created artifact” option.
   
   Acceptance criteria:
   
   After “Create Sub-Pipeline/Mapping”, the editor replaces the selection with 
one reference step.
   
   External connections remain valid and runtime behavior is unchanged.
   
   For multiple entry/exit points, the UI provides consistent ports or clear 
validation guidance.
   
   Rationale (why this matters):
   
   Speed: eliminates repetitive manual extraction work.
   
   Consistency: promotes modular design and reuse.
   
   Maintainability: keeps main pipelines readable and easier to evolve.
   
   Reliability: automated rewiring reduces configuration mistakes.
