[v0.0.5] Implement Resource Texture Management

[jacuzzicoding]

Description

Create a centralized texture management system to avoid duplicated texture creation and improve performance. Currently, textures are created in multiple places, sometimes during rendering, which is inefficient and can lead to resource leaks.

Requirements

• Create TextureManager for loading and caching textures
• Implement texture atlas support for UI elements
• Add reference counting for shared textures
• Ensure proper disposal of unused textures
• Create utility methods for common texture operations

Technical Details

Current issues:

• Multiple instances of the same texture are created
• Textures are created during rendering in some cases
• No consistent approach to texture reuse
• Potential memory leaks from undisposed textures

Acceptance Criteria

• TextureManager handles all texture loading and caching
• UI components use shared textures from TextureManager
• Texture atlas system improves rendering performance
• No textures are created during rendering phases
• Memory usage is reduced due to texture sharing
• Proper cleanup of textures when no longer needed
