Summary

close #19656

This commit adds an index to the conversation_id column in the workflow_conversation_variables table to improve query performance when filtering by conversation ID. This is particularly important for API endpoints that retrieve conversation variables for a specific conversation.

The index is created via a new migration file and will help optimize database queries as the application scales with more conversations and variables.
