Add "Workout Recommendation Generator" Feature

[Diyabaghla]

Enhance the personal gym chatbot by adding a Workout Recommendation Generator.
The chatbot should suggest a personalized workout routine (Beginner, Intermediate, Advanced) based on user input such as fitness goal (e.g., weight loss, muscle gain, endurance) and available time per day.

Tasks:

Add a sidebar section for workout preferences (fitness goal, time availability, experience level).

Generate structured workout recommendations using the selected AI model.

Display the workout plan in a styled Streamlit component (cards or table).

Option to download workout plan as a text/CSV file.
