docs: Update FUTURE_ARCHITECTURE.md with AWS serverless evolution roadmap from v1.0 baseline

[Copilot]

Pull Request Description

Updates FUTURE_ARCHITECTURE.md to reflect v1.0 baseline achievements and comprehensive AWS serverless evolution strategy. Replaces generic backend concepts with detailed AWS-native architecture aligned with Hack23's AWS strategic partnership.

Architecture Evolution

v1.0 Baseline (Current)

• React 19.2.0, TypeScript 5.9.3 strict mode, 83.26% coverage, 175KB bundle
• Frontend-only, client-side assessment, SLSA Level 3 attestation

v2.0 AWS Serverless (Target)

• Lambda functions (Node.js 20.x, Python 3.12), API Gateway (REST/GraphQL)
• Multi-region DynamoDB Global Tables (us-east-1, eu-west-1, ap-southeast-1)
• CloudFront + WAF, Cognito auth with MFA, EventBridge event-driven architecture

AWS Well-Architected Framework Alignment

Complete implementation specifications for all five pillars:

• Security: Cognito identity, GuardDuty detection, WAF protection, KMS encryption, EventBridge incident response
• Reliability: Multi-AZ deployment, Global Tables auto-replication (<1s latency), Resilience Hub testing
• Performance: Lambda optimization, DynamoDB on-demand, CloudFront edge caching, X-Ray tracing
• Cost: Pay-per-use pricing, auto-scaling to zero, savings plans, S3 lifecycle policies
• Operations: CloudFormation/CDK IaC, automated testing, EventBridge automation, multi-account strategy

Multi-Region Data Architecture

# DynamoDB Global Tables Configuration
Regions:
  Primary: us-east-1
  Secondary: eu-west-1, ap-southeast-1
  
Performance:
  Latency: <10ms single-region, <1s replication
  Availability: 99.99% SLA
  Recovery: RTO <1min, RPO 5min, 35-day PITR

Migration Roadmap & Economics

Phase	Duration	Investment	Deliverables
Phase 1	0-6 months	$10,200	Backend API, Cognito auth, DynamoDB
Phase 2	6-12 months	$21,600	Multi-region, GuardDuty, Security Hub, SageMaker ML
Phase 3	12-18 months	$28,800	Resilience Hub, CloudWatch, enterprise integrations
Phase 4	18-24 months	$38,400	QuickSight BI, AppSync GraphQL, advanced analytics

3-Year TCO: Traditional $270K vs AWS Serverless $105K = $165K savings (61%)

Security Architecture

• AWS Cognito: MFA, federated SSO, adaptive authentication
• API Gateway: JWT authorization, rate limiting, request validation
• WAF: OWASP Top 10 rule sets, bot control, geo-blocking
• GuardDuty + Security Hub: Continuous threat detection, CIS/PCI DSS/ISO 27001 compliance
• KMS + Secrets Manager: Encryption at rest/transit, automatic credential rotation
• VPC: Private subnets, VPC endpoints, security groups, NACLs

AWS Resilience Hub Integration

Automated operational readiness with tiered recovery objectives:

• Critical (assessment data, auth): RTO 1h, RPO 5min
• Standard (analytics, reports): RTO 4h, RPO 15min
• Non-Critical (archives, ML training): RTO 24h, RPO 1h

Monthly automated failover testing, CloudFormation-driven remediation.

Documentation Enhancements

• 11 Mermaid diagrams (C4 context, container, component views)
• 103 organized sections covering architecture, security, operations, costs
• 15+ specification tables with performance targets and service configurations
• Complete cross-references to ARCHITECTURE.md, SECURITY_ARCHITECTURE.md, FUTURE_SECURITY_ARCHITECTURE.md

<issue_title>🚀 Update FUTURE_ARCHITECTURE.md based on v1.0 baseline and roadmap</issue_title>
<issue_description>## 🎯 Objective

Update FUTURE_ARCHITECTURE.md with comprehensive architectural evolution roadmap based on accurate v1.0 baseline, reflecting realistic technical improvements, infrastructure enhancements, and strategic technology adoption plans.

📋 Background

Per Secure Development Policy §10, future architecture documentation must be grounded in current state reality with clear evolution paths and technical justification.

Why This Matters:

• ISO 27001 (A.14.1): Change management planning
• NIST CSF (ID.AM-6): Technology development strategy
• CIS Controls (4.1): Secure configuration management planning
• v1.0 Release: Roadmap clarity guides post-release development

📊 Current State (Measured Metrics)

Current FUTURE_ARCHITECTURE.md Status:

• File Size: 35KB (vision document exists)
• Last Updated: Based on v0.8.x architecture
• Gap: Needs update to reflect v1.0 achievements and realistic next steps
• Focus: Backend integration, advanced features, scalability

v1.0 Achievements (Baseline for Future):

• ✅ React 19.x with error boundaries
• ✅ Cypress 15.x E2E testing
• ✅ 81% test coverage (exceeds target)
• ✅ <180KB bundle size
• ✅ SLSA Level 3 attestation
• ✅ CSP security headers

Realistic Future Directions:

• Backend Options: GraphQL API, REST API, or serverless functions
• Data Persistence: IndexedDB for client-side, PostgreSQL for server-side
• Enhanced Analytics: ML-powered compliance recommendations
• Multi-tenancy: Organization-level data isolation
• Real-time Collaboration: WebSocket integration
• Advanced Visualization: 3D risk landscapes, interactive simulations

✅ Acceptance Criteria

• Update baseline assumptions from v1.0 architecture
• Document backend integration options (GraphQL vs REST)
• Add data persistence architecture proposals
• Document scalability and performance targets
• Add ML/AI integration architecture
• Document multi-tenancy design patterns
• Add real-time collaboration architecture
• Document advanced visualization components
• Include migration paths from v1.0
• Add infrastructure evolution diagrams
• Document technology evaluation criteria
• Include ROI analysis for major changes
• Add risk assessment for architectural shifts
• Include cross-references to current ARCHITECTURE.md
