Fix CPU throttling to use 25% of cores and 60s threshold

Browse Source 
- Change idle threshold from 5 minutes to 60 seconds
- Calculate 25% of total cores instead of hardcoded 2 cores
- Update logging message to reflect 25% usage
- Add algorithm include for std::max function
- Ensure minimum 1 core is always used
