InteractiveGrid is a Godot 4.5 GDExtension that allows player interaction with a 3D grid, including cell selection, pathfinding, and hover highlights.

Features:

- Fully compatible with Godot 4.5.
- Highlight cells when hovering the mouse over them.
- Select individual cells.
- Calculate paths from a global position to selected cells using AStar2D.
- Choose movement type: orthogonal (4 directions) or diagonal (8 directions) directly from the editor.
- Customize the grid from the editor: grid size, cell size, mesh, colors, and shaders.
- High performance using MultiMeshInstance3D for efficient rendering of multiple cells.
- Detect obstacles (collision mask configurable from the editor).
- Align cells with the floor (collision mask configurable from the editor).
- Hide distant cells to focus on the relevant area.
