feat(cache): WP Fastest Cache statt WP Super Cache
Die Cache-Integration war für WP Super Cache gebaut, eingesetzt wird aber WP Fastest Cache. Profil (wpfc), Listener, Drosselung, lit/cache-clear und Leeren-Probe laufen jetzt über die öffentlichen WPFC-Funktionen wpfc_clear_post_cache_by_id/wpfc_clear_all_cache; die Probe leert nur die Wegwerf-Seite (singleDeleteCache ohne Elternseiten) und prüft, dass WPFC den Hook noch verarbeitet. Smoke fastest-cache-smoke.sh ersetzt den WPSC-Smoke. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# End-to-end checks of the WP Fastest Cache profile of the compatibility layer: status, check route /wpfc-check with
|

# the purge probe (cache off and on), the purge after a write of this plugin without wp_update_post (terms), the
|
||||
# whole-cache purge after a setting, its throttle, the trailing purge by cron and lit/cache-clear. Runs INSIDE the
|

# DDEV web container:

# SIDE EFFECTS, all undone by the EXIT trap and proven at the end (verify_restored): WP Fastest Cache is activated if

# it was not, its option WpFastestCache is switched (only wpFastestCacheStatus, nothing that writes .htaccess) and set

# back byte for byte, a test post and two categories are created and deleted. Cache files of the site are emptied by

# the whole-cache purges – that is what the run checks; WPFC rebuilds them on the next requests.
