- Added FastAPI backend with core API endpoints for strategies, backtests, and data management. - Introduced Vue 3 frontend with a dark theme, enabling users to run backtests, adjust parameters, and compare results. - Implemented Pydantic schemas for request/response validation and SQLAlchemy models for database interactions. - Enhanced project structure with dedicated modules for services, routers, and components. - Updated dependencies in `pyproject.toml` and `frontend/package.json` to include FastAPI, SQLAlchemy, and Vue-related packages. - Improved `.gitignore` to exclude unnecessary files and directories.
