Summary

Improves interaction clarity by attributing confirmation rows to the acting user and exposing structured select entity arrays.

• append actor mention (<@user>) to confirmation row messages
• preserve existing selected-value labels while adding identity context in-channel
• add structured select entity arrays in payload normalization:
  • selectedUsers
  • selectedChannels
  • selectedConversations
• extend interaction tests for actor-attributed confirmation text and structured selection fields
