Resilience fix - HuggingFace Models Offline mode + keyword capped at 50 chars max (instead of nocap)

• HuggingFace Models Offline mode
  -> the client will initialize itself and download all models, then set itself to offline mode, to never have any interaction with huggingface
  -> goal = no deps on HuggingFace servers

• minor fix on keywords
  they are now capped at 50 chars max, instead of no limit before
