Grant PR Actions Detective write access to issues

[Copilot]

PR Actions Detective was failing to load because the reusable workflow’s nested conclusion and safe_outputs jobs need issues: write, while the trigger workflow only granted issues: read. This blocked the workflow from posting its detection comment on failed PR runs.

• Permissions alignment

  • Updated the trigger workflow to grant issues: write so it matches the permissions required by the called reusable workflow.

• Workflow source sync

  • Applied the same permission change in the workflow template source so future regenerations keep the trigger valid.

permissions:
  actions: read
  contents: read
  copilot-requests: write
  issues: write
  pull-requests: write
