Summary

Restores template variable support for the release workflow, allowing consumers to override GitHub App credentials via template-vars.

All three upstream blockers are now resolved:

common-repo/common-repo#235: source-declared template-vars passthrough (0.28.0)
common-repo/common-repo#239: ${{ }} GHA expression collision fix (0.28.3)
common-repo/common-repo#249: consumer override cache key fix (0.28.4)

Requires common-repo ≥ 0.28.4.

Template Variables

Variable	Default	Purpose
`GH_APP_ID_VAR`	`CHRISTMAS_ISLAND_APP_ID`	GitHub vars name for app ID
`GH_APP_KEY_SECRET`	`CHRISTMAS_ISLAND_PRIVATE_KEY`	GitHub secrets name for app key
`GH_APP_OWNER`	`christmas-island`	GitHub App installation owner

Consumer Override Example

- repo:
    url: https://github.com/christmas-island/cr-semantic-release
    ref: v2.0.0
    with:
      - template-vars:
          GH_APP_ID_VAR: MY_APP_ID
          GH_APP_KEY_SECRET: MY_APP_KEY
          GH_APP_OWNER: my-org

Testing

Verified with common-repo 0.28.4:

✅ Default (no overrides): renders ${{ vars.CHRISTMAS_ISLAND_APP_ID }}
✅ Consumer overrides: renders ${{ vars.MY_CUSTOM_APP_ID }}
✅ ${{ }} expressions preserved untouched
✅ CI sync check updated to skip release.yaml (intentional template vs hardcoded difference)
