Add Copilot code review to orchestrator workflow_run triggers

[microsasa]

Problem

The orchestrator requires a Copilot review before dispatching the quality gate (PR #202). But the orchestrator's workflow_run triggers only monitor: Review Responder, CI Fixer, CI, Quality Gate. It does NOT trigger when Copilot code review completes.

This means after Copilot finishes reviewing, the orchestrator won't fire until the next cron cycle (unreliable) or manual kick.

Fix

Add "Copilot code review" to the workflow_run.workflows list:

workflow_run:
  workflows: ["Review Responder", "CI Fixer", "CI", "Quality Gate", "Copilot code review"]
  types: [completed]

This will trigger on all Copilot reviews (not just aw PRs), but the orchestrator exits quickly when no aw PRs need attention. Public repo has unlimited Actions minutes.
