v1.0.0

Initial public release.

Reusable GitHub Actions workflows and composite actions for the CI/CD pieces every platform team rebuilds from scratch.

Reusable workflows (5): terraform.yml (plan + apply with OIDC, PR comments), docker-build.yml (multi-arch buildx, cosign signing, ECR or GHCR), helm-deploy.yml (lint, template, rollout wait), trivy-scan.yml (image/fs/config scanning with SARIF upload), release-please.yml (conventional commits to releases)

Composite actions (5): setup-tooling (cached install of terraform/helm/kubectl/trivy), aws-oidc-assume, pr-comment (idempotent comment-by-marker), terraform-plan-summary (parses tfplan JSON to markdown), kubectl-deploy (apply + rollout wait)
