Sven Lito 5565f59a1c Fix uvx resource packaging issues for OpenRouter functionality ...

Resolves issues #203, #186, #206, #185 where OpenRouter model registry
completely failed to load in uvx installations due to inaccessible
conf/custom_models.json file.

Changes:
- Implement multiple path resolution strategy in OpenRouterModelRegistry
  - Development: Path(__file__).parent.parent / "conf" / "custom_models.json"
  - UVX working dir: Path("conf/custom_models.json")
  - Current working dir: Path.cwd() / "conf" / "custom_models.json"
- Add importlib-resources fallback for Python < 3.9 compatibility
- Add comprehensive test suite for path resolution scenarios
- Ensure graceful handling when config files are missing

The fix restores full OpenRouter functionality (15 models, 62+ aliases)
for users installing via uvx while maintaining backward compatibility
for development and explicit config scenarios.

Tested: All path resolution scenarios pass, OpenRouter models load correctly
