fix: require the image check for containers

[UnstoppableMango]

unmango/containers ends each of its two workflows in a summary job that needs the rest of that workflow's jobs:

Workflow	Summary context	Gates
CI	build	check (<system>) ×3, manifests
Images	image	enumerate, image (<image>, <arch>) ×10

The real work runs in matrices, which report a context per leg. A ruleset cannot require those without naming every system and every image, so it would need editing here each time an image is added. The summary jobs give two stable names instead.

build was already required, so this only adds image — which is the one that actually gates building every image on both architectures.

Verified

pulumi preview --diff against prod:

    ~ github:index/repositoryRuleset:RepositoryRuleset: (update)
      ~ rules: { ~ requiredStatusChecks: { ~ requiredChecks: [
              + [1]: { + context: "image"  + integrationId: 15368 }
      ] } }

dprint check and make lint pass.

Context: unmango/containers#1.

Summary by CodeRabbit

• Chores

  • Updated repository validation requirements so both build and image checks must pass before changes are accepted.
  • Improved workflow status reporting for matrix-based build and image processes.

• Documentation

  • Added guidance explaining the workflow summary checks and how they represent matrix-based CI and image workflows.

📝 Walkthrough

Walkthrough

The containers repository configuration now requires both build and image summary checks for matrix-based CI and image workflows.

Containers check requirements

Layer / File(s)	Summary
Repository check requirements index.ts	The configuration requires build and image summary checks. Comments document their roles in matrix-based workflows.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to 28f85

The containers repository will require the image summary check in addition to build, ensuring matrix image results gate merges. No merge-blocking risk is evident.

🟢 Approval recommended

The required status check contexts now align with the actual GitHub Actions job names and the change is narrowly scoped to ruleset configuration.

Pull request overview

Updates the GitHub ruleset configuration for the unmango/containers repository so required status checks match the actual GitHub Actions job names produced by CI, preventing PRs from being blocked by a non-existent build context.

Changes:

• Replace the single required check build with the per-system matrix job contexts (build (x86_64-linux), build (aarch64-linux), build (aarch64-darwin)).
• Add manifests and enumerate as additional required checks to align with the repo’s CI/workflow coverage.
