"""ORCH-059 TC-04/05/06: webhook routing for the dedicated "Confirm Deploy"
status vs. the overloaded "Approved".

Contract (AC-2, AC-3, AC-4):
  * TC-04 — handle_issue_updated routes a "Confirm Deploy" status on a `deploy`
    task to the Phase B path (handle_confirm_deploy -> advance_stage with
    confirm_deploy=True), NOT the plain approve/advance path.
  * TC-05 — an "Approved" status on a `deploy` task does NOT initiate the prod
    deploy (self_deploy.initiate_deploy is never called).
  * TC-06 — an "Approved" status on an `analysis` task still advances
    analysis -> architecture (the approved-via-status human gate is intact).
