# Writes .cloud/config.json for a Laravel Cloud app, non-interactively.
#
# Stand-in for `cloud repo:config`, which always prompts for the application
# (no --application flag). Useful in scripts and for bootstrapping new repos.
#
# Usage:
#   cloud-link.sh <app-slug-or-name> [target-dir]
#
# target-dir defaults to the current git repo root (or cwd if not a repo).
# Requires: cloud CLI (authenticated), jq.
