 *     1. GH_TOKEN environment variable
 *     2. GITHUB_TOKEN environment variable
 *     3. `gh auth token` (GitHub CLI — run `gh auth login` once)
 *     4. .env file in repo root (GH_TOKEN=... line)
 *
 * EXAMPLES
 *   php bin/moko health
 *   php bin/moko sync -- --repos MokoDoliTraining --dry-run
