 * BRIEF: Delete lesser pre-release channels from Gitea when promoting stability
 *
 * Usage:
 *   php release_cascade.php --stability stable --token TOKEN --api-base URL
 *   php release_cascade.php --stability rc --token TOKEN --api-base URL
 *
 * Cascade rules:
 *   stable -> deletes development, alpha, beta, release-candidate
 *   rc     -> deletes development, alpha, beta
 *   beta   -> deletes development, alpha
 *   alpha  -> deletes development
