feat: add initial implementation of ECS architecture and systems

- Introduced a minimal Entity-Component-System (ECS) framework in `ecs.ts` with basic entity management and component handling.
- Created `World` class to manage entities and components, including methods for creating, adding, retrieving, and removing components.
- Implemented unit tests for the `World` class in `ecs.test.ts` to ensure functionality.
- Developed input handling with `InputSystem` to capture keyboard events.
- Added `PhysicsSystem` for movement and collision detection.
- Created `RenderSystem` to handle drawing entities on the canvas.
- Set up a main game loop in `main.ts` to integrate systems and manage game state.
- Added SVG icons and images for UI elements.
- Included CSS styles for layout and theming.
- Configured TypeScript settings in `tsconfig.json` for project compilation.
