feat(P27): add Examples section to every module README (D-058)

Each module README (10 primitives + 2 patterns) now has a ## Examples
section before ## Versioning, referencing and excerpting the validated
simple.yaml + complex.yaml (+ mysql.yaml for RDS) example contracts. The
RDS README includes a Multi-engine variation subsection (D-059).

+## Examples
+
+Validated example contracts are in [`examples/`](examples/). The platform-test
+pipeline validates them against `schemas/contract.schema.json`.
+
+### Simple
+
+A minimal deployment (S3 bucket only — no CloudFront/WAF):
+
+[`examples/simple.yaml`](examples/simple.yaml)
+```yaml
+# Simple static-assets deployment (S3 bucket only — no CloudFront/WAF)
+# This is the simplest way to deploy a static site: just an S3 bucket.
+uses: acdl/pipelines/deploy.yaml@v1.6
+module: static-assets
+environment: dev
+inputs:
+  bucket_name: my-static-site
+  region: us-east-1
+```
+
+### Complex
+
+A production deployment with optional inputs (S3 + CloudFront + WAF):
+
+[`examples/complex.yaml`](examples/complex.yaml)
+```yaml
+# Complex static-assets deployment (S3 + CloudFront + WAF)
+# The full production stack: S3 origin + CloudFront CDN edge + WAF protection.
+uses: acdl/pipelines/deploy.yaml@v1.6
+module: static-assets
