Bill 03f81b3b5c feat: add config file loading with error handling
Implement load_config() function with comprehensive error handling
- Loads and parses JSON config files
- Raises ConfigValidationError for missing files
- Raises ConfigValidationError for malformed JSON
- Includes 3 passing tests for all error cases

Test coverage:
- test_load_config_valid_json: Verifies successful JSON parsing
- test_load_config_file_not_found: Validates error on missing file
- test_load_config_invalid_json: Validates error on malformed JSON
