Add comprehensive test suite to improve coverage and fix igdblib bugs

- Add extensive tests for igdblib.py (0% -> 100% coverage expected)
- Add tests for leonardo_draw.py AI image generation
- Add tests for openai_responder.py with GPT integration
- Add tests for discord_bot.py bot functionality
- Add extended tests for ai_responder.py edge cases
- Fix critical bugs in igdblib.py:
  * Fix platforms() method treating name as string instead of list
  * Fix game_info() method missing endpoint parameter
  * Add safe dictionary access with .get() methods

Coverage improvements target areas with lowest coverage to maximize impact.
