feat: implementar sistema RAG Espiritismo completo

- Stack: GPT4All + Llama 3.2 3B, LangChain, Qdrant, FastAPI, Docker
- 11 tarefas implementadas com 100% de conclusão
- Funcionalidades: chat com IA, upload PDF, bot Telegram, agendamento
- 6 livros PDF indexados (A Gênese, Livro dos Espíritos, etc.)
- Documentação rica: README, BUILD, task reports, design specs
- Deploy com Docker Compose
- Production ready

Tech stack:
- AI: GPT4All 2.4.6, Llama 3.2 3B q4_0

+| Plan exists and reachable? | ✅ | `docs/superpowers/plans/2025-11-01-espiritismo-rag-system.md` |
+| Spec exists and reachable? | ✅ | `docs/superpowers/specs/2025-11-01-espiritismo-rag-system-design.md` |
+| Global Constraints present? | ✅ | CPU-only, 8GB RAM, ~5GB storage, Docker, etc. |
+| Tasks independent? | ⚠️ | Many tasks touch common code (embedding, PDF processing) - use batching for small same-shape work |
+| Worktree isolated? | ✅ | Using existing workspace at `lab/espiritismo` |
+
+**Rulings:**
+- Ruling: Use batching for small same-shape work (Tasks 2, 4, 6, 7) — they touch common utilities and can be dispatched together to avoid context pollution. Costs: additional coordination but keeps context clean. Correctness: reduces context churn and improves parallelization.
