  | fix(action): default organization domain at runtime
  | Apply a shell-level default for INPUT_ORGANIZATION_DOMAIN so direct docker
  | execution behaves the same way as the action input definition.
  |
  | This prevents malformed origin URLs in image-mode e2e runs when the variable
  | is omitted and keeps github.com as the effective default.

  fix(workflows): target repository default branch for auto PRs
  Pass github.event.repository.default_branch to action-pull-request in the
  reusable auto-pull-request workflow so repositories using main, master, or a
  different default branch create PRs against the correct base branch.

  This makes the shared auto-PR flow fork-safe for repositories that consume the
  reusable workflow.
