Description

When models are downloaded through Hugging Face search or loaded locally, the app currently infers stop words from the EOS token, but that’s not enough. EOT tokens also need to be included as stop words; otherwise, responses might contain those tokens.

This PR checks if any of these tokens:

   '</s>',
  '<|end|>',
  '<|eot_id|>',
  '<|end_of_text|>',
  '<|im_end|>',
  '<|EOT|>',
  '<|END_OF_TURN_TOKEN|>',
  '<|end_of_turn|>',
  '<|endoftext|>',

are in the chat template and adds them to the stops array if found.

Also we remove tfs_z.
