feat(pipeline): уведомления CI/CD — PipelineWatcher, CI загрузок на Gitea Actions

- app/pipeline: протокол CIProvider, клиент Gitea Actions (прогон по head_sha, упавший
  шаг, лог джоба, ретраи), PipelineWatcher — опрос только при незавершённых push,
  сообщение о push обновляется CI ⏳ → ✅/❌ → CD 🚀/⛔, автору — отдельные уведомления
- деплой сервисов — только после зелёного CI; старый push не откатывает сервис,
  который развернёт более новый; после рестарта бот продолжает с того же места
- CI_PROVIDER=none — прежнее поведение (деплой сразу после push)
- шаблон tgit-uploads: .gitea/workflows/check.yml; .gitea/ защищён от правок из бота
- миграция 0002: старые push помечены skipped, чтобы не слать им «таймаут CI»
- ADR-016, ARCHITECTURE §2.5/§5.2, README, DEPLOY, .env.example
