Release v1.223.0-rc.2 · cloudposse/atmos

## what

Add Atmos-native Markdown summaries for container image build and push operations, including rich inspected image metadata, digest selection, runtime/env/label/layer details, and raw inspect JSON.
Wire summaries into workflow container steps and atmos container build/push component commands behind existing ci.enabled and ci.summary.enabled controls.
Add unit coverage plus a GitHub Actions container-step assertion that verifies the job summary is produced in CI.

why

Lets native Atmos container CI produce the same polished image summary without requiring an additional GitHub Action.
Makes pushed image digests and runtime metadata visible directly in CI job summaries while keeping inspect/write failures best-effort.

New Features
- Container build/push steps now emit native GitHub Actions job summaries with rich image details (refs/tags, digests, image ID, size, runtime/OCI metadata, env, labels, layer digests, and formatted raw inspect JSON).
- Extended workflow steps now receive the active configuration during execution.
Bug Fixes
- Push summaries are generated per successfully pushed reference (including digest when available) and skipped when CI summaries are disabled or unavailable; summary/inspect failures are handled best-effort.
- Rendering is more complete and deterministic.
Documentation
- Added a blog post and roadmap entry covering native container image CI summaries and controls.

## what

Redesign the Atmos CI comment badge served from the existing atmos-ci-gradient image paths as compact GitHub-style light and dark SVGs.
Update Terraform CI plan/apply summaries to render the badge with GitHub's <picture> / prefers-color-scheme responsive image pattern.
Preserve the previous alien-head CI lockups under new media-kit asset names and expose both badge and lockup variants in the media kit.
Refresh CI summary golden files and checked fixtures for the new markup.

Makes Atmos CI branding fit GitHub PR comments better without changing the public comment image URL.
Lets GitHub choose the correct badge artwork for light and dark themes.
Keeps the prior CI lockup available for other brand/media-kit uses.

Validated with pnpm generate:media-kit, SVG render checks, go test ./pkg/ci/plugins/terraform, go test ./tests -run 'Test.*Terraform.*CI|Test.*NativeCI|Test.*PlanCI', and pnpm build.
Commit hooks were retried after building custom-gcl; golangci-lint --new-from-rev=origin/main still reports existing unrelated lint findings outside this change set.

New Features
- CI banners and badges now adapt to light and dark color schemes for a better viewing experience.
- Added new downloadable CI badge and lockup artwork variants in the media kit.
Documentation
- Updated media kit descriptions and badge alt text to use clearer, more specific wording.
