Re-deploy after a FAILED prod deploy wedged the task on `deploy`: the
sentinel markers (approve-requested/initiated/result) are keyed by the
stable work_item_id, so after the БАГ-8 rollback (deploy -> development)
and a developer fix, Phase B's idempotency-guard saw a STALE `initiated`
and became a no-op — the detached hook never re-launched and the
finalizer was never enqueued. Add self_deploy.clear_state (never-raise,
idempotent) and call it on the check_deploy_status FAILED rollback and at
the start of Phase A, so every fresh prod-deploy pass starts clean.
Also document the new ORCH_SELF_DEPLOY_* / ORCH_DEPLOY_* descriptors in
the canonical .env.example (CLAUDE.md rule #8, ТЗ §2.6), modelled on the
ORCH-043 merge-gate block (placeholders only, secrets not committed).
Contracts untouched: STAGE_TRANSITIONS, QG_CHECKS, _parse_deploy_status,
БАГ-8, merge-gate.
