#!/usr/bin/env bash
# Generic deploy orchestrator: runs deploy.hooks.phases from projects/<id>/conf.json (paths relative to repository_root).
# If phases is empty or missing, exec deploy.deploy_script_path with the same arguments.
# Business logic (Prisma, systemd, remote layout) stays in each project's scripts under repository_root.
# Usage: orchestrator.sh <env> [options passed to each phase / fallback script]
# Requires: IA_PROJECT_ID, IA_DEV_ROOT (or re-exec from project root like change-to-all-branches).
