Godot Tactical RPG V2.0

Details

@mbusson made the project structure more scalable (shared assets architecture):

• Models: Centralized storage for class parameters & logic
• Modules: Self-contained reusable units (Godot Nodes)
• Dedicated maps directory
• Adapted code to follow
• Slightly optimized framework performance
• Port to Godot Engine v4.3

PR & Issues:

• #16 -> Shared assets architecture.
