Use COPILOT_GITHUB_TOKEN for Copilot task data collection in centralization optimizer

[Copilot]

The Copilot Centralization Optimizer workflow failed during task collection because it authenticated the Copilot Agents API with github.token, which is not accepted by that endpoint. This change switches that step to a dedicated Copilot user token secret.

• Problem addressed

  • Collect agent task data called gh api /agents/repos/.../tasks with GH_TOKEN: ${{ github.token }}, causing 401s for endpoints that require a Copilot-eligible user token.

• Workflow auth update

  • In copilot-centralization-optimizer.md, updated the step environment to use:
    • GH_TOKEN: ${{ secrets.COPILOT_GITHUB_TOKEN }}
  • Recompiled workflow output to propagate the same change into copilot-centralization-optimizer.lock.yml.

• Scope

  • No behavioral changes outside the task-collection authentication path.
  • This PR is limited to the centralization optimizer workflow source + generated lock file.

# before
env:
  GH_TOKEN: ${{ github.token }}

# after
env:
  GH_TOKEN: ${{ secrets.COPILOT_GITHUB_TOKEN }}

Pull request overview

Updates the Copilot Centralization Optimizer workflow to authenticate the Copilot Agents API task-collection call with a Copilot-eligible user token (secrets.COPILOT_GITHUB_TOKEN) instead of github.token, resolving 401s during agent task data collection.

Changes:

• Switched Collect agent task data to use GH_TOKEN: ${{ secrets.COPILOT_GITHUB_TOKEN }} in the workflow source.
• Recompiled the workflow so the generated .lock.yml uses the same token and includes COPILOT_GITHUB_TOKEN in the manifest + log-redaction secret list.
