refactor: simplify step input structure by removing run key and using context.flowInput

Simplify Step Input Structure for Better Context Access

This PR changes how inputs are passed to steps in a workflow:

1. Removed the run key from step inputs:

   • Previously, all steps received the original flow input under a run key
   • Now, steps access the original flow input via context.flowInput instead

2. Simplified input structure:

   • Root steps (with no dependencies) now receive an empty object {}
   • Dependent steps only receive outputs from their dependencies

3. Updated documentation comments to reflect the new input structure:

   • Added examples for both root steps and dependent steps
   • Clarified that flow_input is available separately in the context

4. Updated tests to verify the new input structure works correctly with:

   • Basic aggregation
   • Mixed dependencies
   • Multiple maps to single step

This change makes the input structure cleaner and more intuitive while ensuring all steps still have access to the original flow input when needed.
