➕ Math Utilities Module

Browse source 
## 🆕 New Math Functions
- 🔢 Added `ft_max` → returns the maximum of two values.  
- 🔢 Added `ft_min` → returns the minimum of two values.  
- ✖️ Added `ft_power` → computes exponentiation.  
- ➖ Added `ft_abs` → returns absolute value.  
- √ Added `ft_sqrt` → computes integer square root.  
- 📄 Created `math.h` to declare and document all math functions.  

## 🛠️ Build System Integration
- 🧩 Updated the `Makefile` to include the new `math/` sources so they compile and link with the rest of the project.  

## ⚡ Impact
- Project now includes a **dedicated math utility module**.  
- Provides essential helper functions for broader use in future features.  
- Cleaner organization with centralized declarations in `math.h`.
