chore: initial monorepo scaffold + WDS Phase 1+2 artifacts

- Nx 22.7 monorepo (pnpm 11.1, TypeScript 5.9, Node 24)
- apps/api: NestJS 11 (CJS conforme CODING-RULES.md PGD-DB-004)
- apps/web: React 19 + Vite 8 (ESM)
- libs/shared/api-interface: Zod contract base
- Docker Compose dev: Postgres 18, Valkey 8, MinIO, Mailpit
- WDS artifacts:
  - design-artifacts/A-Product-Brief/ (5 docs canônicos + 16 dialogs)
  - design-artifacts/B-Trigger-Map/ (hub + 4 personas + feature impact)
- Stack canon: STACK.md v2.2 + CODING-RULES.md v2.0 + brand.md
- AGENTS.md + README.md como entrada para devs/agentes

+# Subagent 4C: Reliability NFR Evidence Audit
+
+## SUBAGENT CONTEXT
+
+This is an **isolated subagent** running in parallel with other NFR domain evidence audits.
+
+**Your task:** Assess RELIABILITY NFR domain only.
+
+---
+
+## SUBAGENT TASK
+
+### 1. Reliability Evidence Audit Categories
+
+**A) Error Handling:**
+
+- Try-catch blocks for critical operations
+- Graceful degradation
+- Circuit breakers
+- Retry mechanisms
+
+**B) Monitoring & Observability:**
+
+- Logging implementation
+- Error tracking (Sentry/Datadog)
+- Health check endpoints
+- Alerting systems
+
+**C) Fault Tolerance:**
+
+- Database failover
+- Service redundancy
+- Backup strategies
+- Disaster recovery plan
+
+**D) Uptime & Availability:**
+
+- SLA targets
+- Historical uptime
+- Incident response
+
