# ia_dev orchestrator: applies shared methodology, then invokes exactly one project orchestrator
# (deploy.project_orchestrator_path relative to repository_root), which sequences project-specific scripts.
# Legacy: if project_orchestrator_path is absent, falls back to deploy.hooks.phases or deploy.deploy_script_path.
# Usage: orchestrator.sh <env> [options…] — passed unchanged to the project orchestrator.
# Requires: IA_PROJECT_ID, IA_DEV_ROOT (or callers like change-to-all-branches).
