v0.9.2

Fixed

• Malformed Tool Token Detection - Detect and retry when models output raw internal tokens
  • Some models (especially Hermes/ChatML-style) output raw tokens like <|start|>assistant<|channel|>... instead of proper responses
  • New _contains_malformed_tool_tokens() method detects these patterns
  • Final response generation now retries once with a stern instruction if malformed tokens detected
  • Falls back to error response if retry also fails
  • Prevents garbage output from reaching users
