Fixed

Tool call results: Fixed HTML entities like ", &, ' not being decoded before sending to LLM
Previously, tool results were stored with HTML-escaped content and retrieved from DB with entities still present
Now processDetails() properly decodes HTML entities before inserting tool call results into messages
This ensures the LLM receives clean JSON instead of malformed escaped entities
