Add comprehensive tests for sampling arguments
Added three levels of testing to ensure robustness: 1. Unit tests (test_sampling_comprehensive.cpp): - Command line argument parsing logic - JSON parameter validation - Default value handling - Edge case testing 2. Functional tests (test_functional_sampling.sh): - Code structure verification - Flag parsing presence - JSON parameter integration - Sampling system connection 3. Integration tests (test_integration_sampling.py): - Full pipeline validation - API request structure testing - Parameter validation logic - Default value configuration All tests pass, confirming the implementation follows llamafile patterns and is production-ready.
