Description

The current configuration handling in the script relies on multiple sources (environment variables, a JSON config file, and default values). However, there are potential issues that could lead to unexpected behavior:

1. Missing Config File Handling: If the config file does not exist, the script attempts to load it, which may cause errors.
2. Error Handling for JSON Parsing: If the config file is malformed, the script does not handle the JSON parsing errors gracefully.
3. Redundant Environment Variable Checks: The script checks for environment variables multiple times in different locations, which could be streamlined.
4. Logging Instead of Silent Failures: Errors or missing configurations should be logged for better debugging.

Steps to Reproduce

1. Remove the config.json file or set ROBOFLOW_CONFIG_DIR to a non-existent path.
2. Run the script and observe any failures.
3. Modify config.json to contain invalid JSON.
4. Run the script again and observe the error handling.

Expected Behavior

• The script should handle missing or malformed config files gracefully.
• It should provide clear logs when a configuration value cannot be retrieved.
• Environment variable lookups should be optimized.
