* fixes setup scripts
fixes to env handling in setup script plus other minor fixes
* Remove var declarations
Declarations such as `LLM_PROVIDER=$LLM_PROVIDER` override .env variables in compose
Similar issue is present in the frontend - need to choose either to switch to separate frontend env or keep as is.
* Manage apikeys in settings
1. More pydantic management of api keys.
2. Clean up of variable declarations from docker compose files, used to block .env imports. Now should be managed ether by settings.py defaults or .env
* feat: Implement model registry and capabilities for multi-provider support
- Added ModelRegistry to manage available models and their capabilities.
- Introduced ModelProvider enum for different LLM providers.
- Created ModelCapabilities dataclass to define model features.
- Implemented methods to load models based on API keys and settings.
- Added utility functions for model management in model_utils.py.
- Updated settings.py to include provider-specific API keys.
- Refactored LLM classes (Anthropic, OpenAI, Google, etc.) to utilize new model registry.
- Enhanced utility functions to handle token limits and model validation.
- Improved code structure and logging for better maintainability.
* feat: Add model selection feature with API integration and UI component
* feat: Add model selection and default model functionality in agent management
