What's Changed

EKS addons — CreateAddon, DescribeAddon, ListAddons, UpdateAddon, DeleteAddon at /clusters/{name}/addons[/{addonName}[/update]]. Status flips to ACTIVE on create / update (the same shortcut the nodegroup path already uses — Terraform polls until ACTIVE so a slow-roll status would only stall plans). Tags + persistence wired through the existing patterns. Unblocks aws_eks_addon for the standard cluster bootstrap (vpc-cni, coredns, kube-proxy, aws-ebs-csi-driver). Reported by @b-rajesh.

API Gateway Lambda-proxy Set-Cookie and multiValueHeaders now reach the client — v2 maps the payload-format-2.0 cookies array to a list-valued Set-Cookie (RFC 6265 §3 forbids comma-folding); v1 folds the format-1.0 multiValueHeaders into the response with multiValueHeaders winning over headers on key collision per the AWS contract; app.py:_send_response expands list-valued headers into one wire line per entry. Collision check is case-insensitive (HTTP headers are case-insensitive per RFC 7230 §3.2), so Set-Cookie in headers plus set-cookie in multiValueHeaders correctly resolves to MVH wins instead of shipping both.

DynamoDB data-plane table-name length range — PutItem / GetItem / UpdateItem / DeleteItem / Query / Scan now accept the AWS-documented 1..255 range (the 3-char minimum is a control-plane-only rule on CreateTable). NULL-attribute error message text aligned to "Null attribute value types must have the value of true".
EC2 launch template version XML shape — CreateLaunchTemplateVersion returns a single <launchTemplateVersion> struct; DescribeLaunchTemplateVersions wraps the same struct in <launchTemplateVersionSet><item>…</item></launchTemplateVersionSet>. The <item> wrapper now belongs at the list-context boundary, not on the inner struct — matching the AWS Query-protocol response. Reported by @b-rajesh.
