Cards CI workflows

Reusable GitHub workflows for building and releasing webapp cards.
Cards should reference these workflows via tags so they can pin to a known-good version or track the latest stable release.

Using the workflow

jobs:
  release:
    uses: InTouchSO/cards-ci/.github/workflows/card-release.yml@stable
    with:
      node-version: '20'
    secrets:
      WEBAPP_DEPLOY_TOKEN: ${{ secrets.WEBAPP_DEPLOY_TOKEN }}

• Use a concrete tag such as @v1.2.3 to pin to an exact release.
• Use the movable @stable tag to always consume the most recent version.

Publishing new versions

1. Merge your workflow changes to release.
2. Open Actions → Publish Workflow Version and run the workflow:
   • version: SemVer string (v1.2.3 or 1.2.3).
   • mark-stable: Set to true only if this version should become the new stable.
3. The workflow creates (and pushes) the annotated vX.Y.Z tag.
   When mark-stable is true, it also force-updates the stable tag to the same commit.

Consumers can immediately reference the new vX.Y.Z tag or opt into the refreshed stable tag.
