Add a standalone style guide document

Moved the CIGUI style guide from `README.md` to a dedicated `StyleGuide.md` file for better organization. This improves readability and ensures the main README remains focused on project goals and usage.

-## CIGUI Style Guide
-
-This document outlines the coding standards and best practices for the CIGUI library. Following these guidelines ensures consistency across the project and makes the codebase more maintainable.
-
-### General Principles
-
- **Clarity over cleverness**: Write code that's easy to understand, not code that's clever.
- **Consistency**: Follow established patterns within the codebase.
- **Documentation**: Document public APIs thoroughly.
- **Testability**: Write code that can be easily tested.
-
-### Naming Conventions
-
-#### Files
-
- Header files: `.hpp` for C++ headers, `.h` for C-compatible headers
- Implementation files: `.cpp`
- Template implementation files: `.inl`
- File names: lowercase with underscores (e.g., `grid_layout.hpp`)
-
-#### Classes and Types
-
- Class names: PascalCase (e.g., `Button`, `GridLayout`)
- Type aliases/typedefs: PascalCase (e.g., `using WidgetPtr = std::shared_ptr<View>`)
- Enum names: PascalCase
- Enum values: PascalCase (e.g., `enum class Alignment { TopLeft, Center, BottomRight }`)
-
-#### Functions and Variables
-
- Function names: camelCase (e.g., `getPosition()`, `setVisible()`)
- Variable names: camelCase (e.g., `buttonText`, `isVisible`)
- Member variables: prefix with `m_` (e.g., `m_position`, `m_size`)
- Static variables: prefix with `s_` (e.g., `s_defaultFont`)
- Constants and macros: ALL_CAPS with underscores (e.g., `MAX_WIDGETS`, `CIGUI_API`)
-
-### Code Structure
-
-#### Namespaces
-
- All library code should be inside the `cig` namespace
- Avoid deeply nested namespaces
- Do not use `using namespace` in headers
-
-```cpp
-// Good
-namespace cig {
-    class Button : public View {
-        // ...
-    };
-}
-
-// Bad
-using namespace sf;  // Don't do this in headers
-```
-
-#### Headers
-
- Always use include guards with project-specific prefix
- Order includes as follows:
-    1. Related header
-    2. C++ standard library headers
-    3. Third-party library headers (SFML)
-    4. CIGUI headers
- Forward declare classes when possible to reduce dependencies
-
-```cpp
-// Example of a good header structure
-#pragma once
-
-#include <cigui/config.h>
-#include <string>
-#include <vector>
-#include <SFML/Graphics/Drawable.hpp>
-#include <cigui/utils/rect.hpp>
-
-namespace cig {
-
-class View;  // Forward declaration
-
-class CIGUI_API Container {
-    // Implementation
-};
-
-}  // namespace cig
-```
-
-#### Classes
-
- Separate public, protected, and private sections
- Order within sections:
-    1. Constructors/Destructors
-    2. Public methods
-    3. Event callbacks
-    4. Static methods
-    5. Member variables
-
-```cpp
-class Button : public View {
-public:
-    // Constructors/Destructors
-    Button();
-    explicit Button(const std::string& text);
-    ~Button() override;
-
-    // Methods
-    void setText(const std::string& text);
-    const std::string& getText() const;
-
-    // Event dispatcher
-    EventDispatcher<MouseEvent> onClicked;
-
-protected:
-    // Protected methods
-    void updateAppearance();
-
-private:
-    // Private methods
-    void initializeGraphics();
-
-    // Member variables
-    std::string m_text;
-    sf::RectangleShape m_background;
-    bool m_isHovered;
-};
-```
-
-### Templates
-
- Template implementation should be in `.inl` files
- Use explicit instantiation for common types in DLLs
- Document template parameters
-
-```cpp
-// In .hpp file
-template<typename T>
-class Container {
-    // ...
-};
-
-// Include the implementation
-#include <cigui/widgets/container.inl>
-
-// In .inl file
-template<typename T>
-Container<T>::Container() {
-    // ...
-}
-
-// In .cpp file for explicit instantiation
-template class Container<int>;
-template class Container<std::string>;
-```
-
-### C++ Features
-
- **C++ Standard**: Use C++20 features where appropriate
- **Smart Pointers**: Use `std::unique_ptr` for exclusive ownership, `std::shared_ptr` for shared ownership
- **Auto**: Use `auto` when the type is obvious or when using iterators
- **Range-based for loops**: Prefer over traditional for loops
- **Lambdas**: Use for short callbacks and event handlers
- **Move Semantics**: Support move operations where appropriate
-
-### Comments and Documentation
-
- Use Doxygen-style comments for public APIs
- Comment complex algorithms and non-obvious code
- Avoid redundant comments that just repeat the code
-
-```cpp
-/**
- * @brief Creates a button with the specified label text
- * 
- * @param text The text to display on the button
- * @param size The size of the button (default: 100x30)
- */
-Button(const std::string& text, const sf::Vector2f& size = {100.f, 30.f});
-```
-
-### Error Handling
-
- Use exceptions for exceptional cases only
- Validate input parameters and handle edge cases
- Document error conditions in function comments
-
-### Memory Management
-
- Prefer automatic memory management with smart pointers
- Explicitly define ownership models in documentation
- Design with RAII principles (Resource Acquisition Is Initialization)
-
-### DLL/Shared Library Considerations
-
- Use `CIGUI_API` macro for all classes and non-inline functions
- Use `CIGUI_TEMPLATE_API` for template classes
- Handle template instantiation properly (see Templates section)
-
-### SFML Integration
-
- Wrap SFML types when extending functionality
- Use SFML conventions for graphics-related code
- Don't expose SFML implementation details in public APIs when avoidable
-
-### Testing
-
- Write unit tests for core functionality
- Test edge cases and error conditions
- Create interactive examples for UI components
-
-### Formatting
-
- Indentation: 4 spaces (no tabs)
- Line length: 100 characters maximum
- Braces: Open brace on same line, close brace on new line
- Space after keywords (if, for, while)
- No space after function names
- Place * and & with the type, not the variable name
-
-```cpp
-// Good formatting example
-if (condition) {
-    doSomething();
-} else {
-    doSomethingElse();
-}
-
-void setPosition(const sf::Vector2f& position) {
-    m_position = position;
-}
-```
-
-### Best Practices
-
- Prefer composition over inheritance
- Design interfaces that are hard to use incorrectly
- Follow the Rule of Five/Zero for class design
- Make data members private and provide accessors when needed
- Consider performance implications in UI code (avoid work in draw methods)
-
---
-
-This style guide is a living document and may evolve as the project grows. When in doubt, maintain consistency with the existing codebase.
