Neue PSR-15-Middleware ClientErrorMiddleware: nimmt Browser-Fehler des
React-Frontends als JSON {url, message, stack, release, userAgent}
entgegen und antwortet 204 ohne Body. Schutz: 30 Meldungen pro Minute
und IP (Sliding Window ueber TYPO3-RateLimiter, 429 + Retry-After),
8-KB-Body-Limit (413, Content-Length und tatsaechliche Bytes), kein
JSON-Objekt oder leere message = 400, GET = 405. Keine Session, keine
Cookies; der /_json-Praefix funktioniert ebenfalls.
Speicherung in der neuen Tabelle tx_vitec_clienterrorlog mit
anonymisierter IP (IPv4 letztes Oktett 0, IPv6 /48). Sichtbar als
Tabelle "Client errors (last 24 h)" im Modul VITEC SSR (mit Stack als
Aufklapper) und als Zeile "Client errors reported (24 h / 7 d)" in der
Dashboard-Kachel VITEC: SSR statistics.
CLI vitec:client-error-cleanup [--days=30] loescht Eintraege aelter als
30 Tage (taeglich per Cron).
