Subject: [PATCH] Fix Debrid-Link key rotation: skip broken keys immediately,
 add cooldown cache

- Add "notDebrid", "disabledServerHost", "notFree" as immediate-skip errors
  (no 3x retry per key, break to next key instantly like quota errors)
- Add per-key cooldown cache (2 min) so parallel items skip recently-failed keys
  instead of all starting at the same broken key
- Set cooldown on quota errors too, preventing repeated checks on exhausted keys
