const HELP = `Usage: apply.mjs <answers.json> [--overwrite] [--dry-run] [--project-root <path>]

Applies the answers in answers.json and writes the five git workflow files
(runs paqad-ai git-workflow setup --apply).

Arguments:
  <answers.json>         the answers file, started from assets/answers.template.json

Flags:
  --overwrite            replace git workflow files that already exist
  --dry-run              print the diff and the validation result, and write nothing
  --project-root <path>  the project root (default: the current folder)
  --help                 print this help

Prints JSON. Exits 0 on success, 1 on invalid answers or files, 2 when paqad-ai, git or gh failed.
