Sync repo with internal fork to bring it up to date

Removed duplicated code from sample pipeline

Bring GitHub issue management in line with security-devops-action:
- Label taxonomy with type, priority, status, area, and resolution groups
- Automated label sync workflow with legacy label migration
- Copilot-powered issue triage assistant using wiki knowledge base

Generated by gh aw compile from msdo-issue-assistant.md

- .github/aw/actions-lock.json: pins gh-aw action version
- .gitattributes: marks lock files as linguist-generated with merge=ours

- Rename workflow from MSDO to Issue Triage Assistant
- Remove wiki FAQ.md ref (azdevops repo only has Home.md)
- Fix area labels: task, tools, container-mapping, pipeline
- Remove sync-labels.yml (labels added directly via API)
- Re-compile lock file

Replace legacy label names (bug, needs-info, needs-maintainer) with
the new taxonomy (type:bug, status:waiting-on-author, status:team-review)
in both the safe-outputs allowed list and the prompt instructions.
