Jon Chery a9d8b31595 feat(P27): RDS primitive + adapter expansion (D-059)

Add modules/l1/rds/ with interface.json (engine enum for postgres, mysql,
mariadb, sqlserver, oracle), instance.json, README.md (full template with
compliance extension points). Register in registry.json. Expand the
adapter TYPE_MAP/INPUT_MAP/OUTPUT_MAP for aws:rds:instance -> aws_db_instance;
emit backup_retention_period, deletion_protection, storage_encrypted, and
skip_final_snapshot from NFRs/inputs. Add RDS to the primitives-plan matrix.
Update tests for the new registry entry count (12) + RDS adapter emission.

ACDL Modules

Reusable building blocks for cloud infrastructure. Each module is self-documented with a README.md following the template.

How the modules work

There are two kinds of module:

Primitives — a single cloud resource or a small group of related resources (e.g. a VPC with subnets and routing). Each primitive has an interface.json declaring its inputs and outputs, and a README.md in plain language.
Modules — a pattern that references multiple primitives to deploy a complete stack (e.g. an ECS Fargate microservice). Each module has a composition.json declaring its children and wires.

The substrate adapter (adapters/terraform/adapter.py) compiles a module instance to infrastructure. Each module's README documents which resources it creates.

Primitives

Module	What it creates	README
`s3`	`aws_s3_bucket` — a single S3 bucket	README
`vpc`	`aws_vpc` + `aws_subnet` + `aws_route_table` + `aws_internet_gateway` — VPC with subnets and routing	README
`ecs-cluster`	`aws_ecs_cluster` — ECS Fargate cluster	README
`ecs-service`	`aws_ecs_task_definition` + `aws_ecs_service` — Fargate service with task definition	README
`iam-role`	`aws_iam_role` — IAM role with assume-role policy	README
`alb`	`aws_lb` + `aws_lb_target_group` + `aws_lb_listener` — Application Load Balancer	README
`ecr`	`aws_ecr_repository` — ECR container image repository	README
`cloudfront`	`aws_cloudfront_distribution` + `aws_cloudfront_origin_access_control` — CloudFront distribution with S3 origin via OAC	README
`waf`	`aws_wafv2_web_acl` — WAFv2 Web ACL (CloudFront-scoped)	README

Modules

Module	What it references	README
`microservice`	6 primitives (vpc, cluster, ecr, iam-role, alb, ecs-service)	README
`static-assets`	3 primitives (s3, cloudfront, waf)	README

Registry

Module versions are tracked in registry.json. Both primitives and modules are registered.

Template

New modules should use README-TEMPLATE.md as their starting point.

Module patterns (roadmap)

The current composition.json mechanism is a thin pattern layer. A future redesign will let a consumer dynamically create a module directly from the contract file (an agentic "composition" flow). That is on the roadmap, not implemented today.
