fix(client): reliable NS-14 click-to-move without NavigationMesh

- Drive movement with horizontal steering + move_and_slide toward click goal
- Remove NavigationRegion3D / NavigationAgent3D; obstacle interaction is slide
- main.gd: raycast to walkable, Player.set_move_goal; viewport camera + mouse
- Scene: explicit physics layers/mask on floor, obstacle, player
- Docs: Godot 4.6 baseline, README + NS-14 plan + tech_stack; Godot .import/.uid

+- Movement is **direct horizontal steering** plus **`move_and_slide()`**: the capsule walks toward the click and **slides along** the center crate instead of pathfinding around it.

+In the **Game** dock, **Input** must be active (not the **2D** / **3D** scene-picking tools) so events go to the game. If Input is on and clicks still do nothing, pick rays must use the **viewport’s current camera** and **mouse position** (the script does this so the embedded Game view matches the ray).
