Refactor PlantSimulator to enhance plant growth modeling and UI

- Introduced new Branch and Fruit interfaces to better represent plant structure.
- Updated PlantState to include branches and fruits, improving growth simulation.
- Enhanced SVG rendering with new gradients and animations for a more dynamic visual experience.
- Adjusted constants for maximum height, yield, and dimensions to improve realism.
- Added helper functions for quadratic bezier calculations to refine plant shape rendering.
