chore: update project structure and add execution and selector modules

- Added new execution modules: Router, Swap0x, SwapCow, SwapParaswap with mocked logic for trade execution.
- Introduced selector modules: AlloraPredictor with API integration and fallback logic, and LLMOverlay for trade vetoing.
- Updated .gitignore to include environment files and coverage directories.
- Modified docker-compose.yml to include new services for alphadrift and driftbrain.
