feat: implement automatic temperature reduction on tool failure

- Add temperature tracking properties to Task class
- Implement temperature reduction logic with configurable factor (0.5)
- Add retry mechanism when tools fail, reducing temperature up to 3 times
- Include temperature information in error messages
- Add comprehensive test coverage for temperature reduction functionality

Fixes #6156
