feat(cache): Verhaltensprobe und Smoke für WP Super Cache

SuperCacheProbe prüft beim Prüfen, ob wp_cache_post_edit die Cache-Datei einer Testseite entfernt; während der Probe ist nur der Einzelseiten-Purge erlaubt, der Pfad kommt aus home und es werden nur feste Dateinamen gelöscht. ProbeStep bündelt die Schrittlogik von Pods und WP Super Cache; ThrowawayPost hält Marker und Titel zentral und räumt auch private Probe-Seiten auf (WP Super Cache wie Pods beim Laden des Reiters). super-cache-smoke.sh prüft gegen das echte Plugin; lib.sh sperrt parallele Smoke-Läufe per flock, wp-config.php wird atomar wiederhergestellt. Doku: Host-Abhängigkeit des Einzel-Purges, WP-Cron für den Nachlauf, Komplett-Purge durch Divi beim Prüfen.

# this plugin without wp_update_post (terms), the whole-cache purge after a setting, its throttle and the trailing
# purge by cron. Runs INSIDE the DDEV web container:

# wp-config.php (WP_CACHE, WPCACHEHOME), creates wp-content/advanced-cache.php and wp-content/wp-cache-config.php,
# fills wp-content/cache/ and schedules wp_cache_* cron events and options. The script saves wp-config.php (and the
