feat: P0-P4 Infrastructure & Documentation Completion (AGENTS.md v16.0)

**P0: DB Isolation** ✅ VERIFIED
- Test appsettings.Development.json uses kartselldb_test (isolated)
- 135/135 tests passing against kartselldb_test

**P1: Gate 3 Data Layer Real Integration** ✅ COMPLETE
- KrxDataService (real) registered in Program.cs
- Fallback to stub data if KRX_API_KEY missing
- No breaking changes to existing code

**P2: Observability Service Integration** ✅ COMPLETE
- ObservabilityService (real) registered in Program.cs
- MetricsSql queries (PIT-based) connected
- Dashboard ready for Gate 3 metrics

**P3: MetricsSql Placeholder Cleanup** ✅ COMPLETE
- GetDuplicateDetectionAsync: Clarified audit trail dependency
- GetReconciliationBreaksAsync: Explained version mismatch correlation need
- GetModelDriftAsync: Documented Gate 3 runnable prerequisite

**P4: Documentation Updates** ✅ COMPLETE
- CURRENT_ROADMAP.md: Gate 3 IN PROGRESS status, real execution steps
- PRODUCTION_READINESS.md: 135/135 tests, 78% ready, Gate 3 rehearsal active
- TECH_DEBT_REGISTER.md: Added DEBT-015 (Hangfire lock resilience)

**Infrastructure Status**
- ✅ Host running (Development mode, port 5002)
- ✅ SSH tunnel active (remote PostgreSQL)
- ✅ Hangfire Job 269 executing (Phase 1-5 in progress)
- ✅ Gate 3 Shadow Run ID: d14f34ea-2afe-4caf-bbb1-c9a7d74fb582
- ⏳ Model operations.shadow_run write pending (Job completion)

**Test Coverage**: 135/135 PASS (5 arch + 95 integration + 35 unit)

**Next**: Gate 3 completion monitoring + P5 tech debt documentation
