Release v1.7.226

Symptom (per Ferndiagnose live verifiziert): Bei nur EINEM Mega-Debrid-Account lief
der Download eine Weile sauber, dann standen schlagartig ALLE Items ~120s im
"Mega-Debrid Cooldown" — obwohl der Account voellig gesund war (andere Links loesten
zeitgleich in 13-18s auf). Jede Cooldown-Zeile zeigte exakt dieselbe Deadline
(20:52:55.901) -> ein einziger account-weiter Cooldown, einmal gesetzt.

Ursache: Laeuft eine Web-Aufloesung laenger als das 60s-Gesamt-Timeout, feuert der
Abbruch-Pfad (debrid.ts) einen 120s-Account-Cooldown. Dessen einziger Zweck (laut
Code-Kommentar) ist, den Retry auf den NAECHSTEN Account rotieren zu lassen. Bei nur
einem Account gibt es keinen naechsten -> stattdessen findet jedes folgende Item den
einzigen Account im Cooldown und wird bis zu 120s geparkt -> die ganze Liste steht.
Ein 60s-Timeout ist ein Signal fuer einen LANGSAMEN LINK, nicht fuer einen
ungesunden Account.

Fix: Der Account-Cooldown wird nur noch gesetzt, wenn es tatsaechlich einen anderen
nutzbaren Account zum Rotieren gibt. Ohne Rotationsziel (Einzel-Account / alle
anderen belegt) wird der Account NICHT mehr eingefroren; stattdessen wird nur der
langsame Link selbst geparkt (mega_debrid_slow_link -> Item-Retry), waehrend alle
anderen Items weiter ueber den gesunden Account laufen. Das Mehr-Account-Verhalten
(Rotation per Account-Cooldown) bleibt unveraendert.

Der baugleiche Debrid-Link-Pfad (Einzel-Key, debrid.ts) ist derselbe Muster-Typ,
aber ein separater, hier nicht genutzter Provider mit eigener Nachbehandlung -
bewusst nicht mitgebuendelt.

Tests: debrid.test.ts (Einzel-Account-Abbruch parkt nur den Link, KEIN
Account-Cooldown, zweites Item loest weiter auf) + unrestrict-retry.test.ts
(parseMegaDebridSlowLinkRetry, keine Token-Kollision). Suite 934 gruen, tsc 6.
