⚡️ Describe the Bug

The application crashes with AttributeError: module 'json' has no attribute 'DecodeError' when trying to load a corrupted or invalid JSON file. This happens because json_manager.py uses the wrong exception name - json.DecodeError doesn't exist in Python's json module.

👣 Steps to Reproduce

1. Create a corrupted JSON file in src/outputs/
2. Try to load it using JsonManager.load_json()
3. Application crashes with AttributeError

📉 Expected Behavior

Should catch the JSON parsing error gracefully and raise an IOError with a helpful message like "Invalid JSON format in file."

🖥️ Environment Information

• OS: Windows 11
• Python: 3.11+
• Docker/Compose Version: N/A
• Ollama Model used: N/A (occurs before LLM interaction)

📋 Error Logs

Traceback (most recent call last):
File "src/json_manager.py", line 14, in load_json
except json.DecodeError:
AttributeError: module 'json' has no attribute 'DecodeError'

🕵️ Possible Fix

Line 14 in src/json_manager.py needs to use json.JSONDecodeError instead of json.DecodeError. The correct exception name in Python's json module is JSONDecodeError, not DecodeError.

One-line fix:
Change line 14 from except json.DecodeError: to except json.JSONDecodeError:
