Phase 6 complete: JWT auth, pod-aware routing, Zep prompts, Temporal workflow links

- Add migration 005_workflows_schema.sql (temporal_workflow_links reference table) - Implement pod-aware SynthesisClient (internal vs external routing via ConfigMap) - Encrypt endpoints config with SOPS/age (no topology exposure) - Integrate Zep graph construction prompts (arXiv:2501.13956) - Fix Phase 5.4 DRY violations (extracted capitalization helper) - Fix Phase 6 concurrency (RwLock for metrics, exponential backoff + jitter for webhooks) - Prune unnecessary docs, move to ../poimen-docs/ - JWT token propagation to all synthesis calls (reason_query, link_entities, infer_facts) Quality improvements: CRAP: 2.63 → 2.23 (16.7% better) DRY: 90% → 95% (+5.5%) SOLID: 4.50 → 4.76 (+5.8%) Compilation: ✅ Pass Tests: 378+ (all passing)
