feat(phase-2): workstream 8 — Multi-Region Terraform Deployment

AWS environment:
- VPC (3-AZ, public + private subnets, NAT gateways, VPC endpoints for ECR/SM/CW)
- ECS Fargate service (sentryagent/agentidp) — secrets from Secrets Manager
- RDS PostgreSQL 14 (Multi-AZ, encrypted, VPC-internal, storage autoscaling)
- ElastiCache Redis 7 (primary + replica, at-rest + in-transit encryption)
- ALB with HTTPS/443, HTTP→HTTPS redirect, ACM certificate
- Route 53 alias record

GCP environment:
- VPC + private services access + Serverless VPC connector
- Cloud Run service — secrets from Secret Manager
- Cloud SQL PostgreSQL 14 (private IP, no public endpoint)
- Cloud Memorystore Redis 7 (VPC-internal, AUTH enabled)

Shared:
- 4 reusable modules: agentidp (dual AWS/GCP), rds, redis, lb
- No hardcoded secrets; all sensitive vars marked sensitive=true
- terraform.tfvars.example for both environments
- docs/devops/deployment.md — AWS + GCP step-by-step walkthrough, rollback procedures
