Minor agent-orchestrator updates (#746)

Tidy agent-orchestrator logs

Added CLI support for selecting the pattern...

  tg-invoke-agent -q "What is the document about?" -p supervisor -v
  tg-invoke-agent -q "What is the document about?" -p plan-then-execute -v
  tg-invoke-agent -q "What is the document about?" -p react -v

Added new event types to tg-show-explain-trace
