Plan: Fix Round Robin Scheme Prompt Syntax

• Update .github/aw/create-agentic-workflow.md to change cache: to cache-memory:
• Update pkg/cli/templates/create-agentic-workflow.md to change cache: to cache-memory:
• Update the scheme implementation guidance to let the authoring agent decide the data format
• Verify changes compile correctly
• Run final validation with make agent-finish

Changes Made

Updated the round-robin processing pattern documentation in both workflow template files:

1. Changed syntax: cache: → cache-memory: true

   • Removed the incorrect nested structure with enabled and keys
   • Now uses the correct MCP server syntax for persistent memory storage

2. Updated implementation guidance:

   • Changed step 2 to: "Read from cache-memory to determine what was processed last (the authoring agent should decide the data format and update the scheme to implement it)"
   • Changed step 5 to: "Update cache-memory before finishing with the current item state"
   • Removed specific examples like cache_get and cache_set to give agents flexibility in implementation

This aligns with the correct cache-memory: tool syntax documented in github-agentic-workflows.md.
