feat(plane): осмысленная статусная модель Plane (слой B — индикация)

Приводит статусы доски Plane к смыслу стадий конвейера, сохраняя
инвариант «статус — индикация, а не управление». Меняется только слой B
(отображение: src/plane_sync.py + точки выставления статуса в
stage_engine.py/webhooks/plane.py/reconciler.py); слой A — машина стадий
src/stages.py::STAGE_TRANSITIONS — остаётся байт-в-байт неизменным (AC-21).

- 6 новых логических ключей статуса (to_analyse, analysis, code_review,
  awaiting_deploy, deploying, monitoring) + сеттеры и диспетчер
  set_issue_stage_state.
- Project-relative alias-fallback (BR-12): новый ключ деградирует на
  базовый UUID того же проекта → нулевая регрессия для enduro-trails.
- Самодеплой (ORCH-036) индицирует фазы: Awaiting Deploy / Deploying;
  terminal-sync для self-hosting → Monitoring after Deploy, для прочих →
  терминальный Done.
- Post-deploy монитор (ORCH-021): HEALTHY → Done, DEGRADED → Blocked
  (только индикация; self-hosting ALERT_ONLY, прод не трогается, BR-5).
- Reconciler: триггер старта/резюма на To Analyse; Guard 2 учитывает
  новые активные ожидания без расширения skip-set на алиасах.
- never-raise контракт сеттеров и резолвера состояний сохранён.
- Раскатка — созданием статусов в Plane оператором, без kill-switch.

Инварианты не менялись: STAGE_TRANSITIONS, QG_CHECKS (12 чеков),
check_deploy_status, exit-код-контракт хука, merge-gate, схема БД.

ADR: docs/work-items/ORCH-066/06-adr/ADR-001-plane-status-model.md
Тесты: test_plane_status_model, test_plane_to_analyse_resume,
test_plane_status_failclosed + TC в существующих наборах. 774 passed.
