New Engine/Core/Input.h/.cpp: static input facade with a Key/MouseButton enum (values map to GLFW key codes internally) so scripts and game logic no longer touch GLFW directly - window backend becomes swappable and the facade is the surface to expose when embedding scripting later. Wired up in Application's constructor; Camera (editor camera WASD/RMB/MMB), the WASDMove script and SandboxApp key handling now query Input only. Ctrl+P hotkey fix: the !m_Playing guard made the hotkey dead exactly when it was needed - after pressing Play. Now toggles both ways. Toolbar Pause button now reads "Resume" while paused (tooltip follows).

// WASDMove.cpp：WASD 控制实体移动（相机水平朝向参考，UE gameplay 语义）。

//
|
||
// 移动语义分派：
|
||
// - Dynamic 刚体 → 走物理速度门面（每帧喂水平速度，Y 归物理——
|
||
// 重力/跳跃不受影响；松键喂零速 = 立即停，Unity velocity 语义）
|
||
// - 无刚体 → 直接平移 Transform
|
||
//
|
||
// 编辑器形态键位天然不冲突：RMB 按住 = 相机吃 WASD 飞行（脚本也读
|
||
// 到按键 → 同时在动，测移动时松开 RMB 即可）；游戏形态 WASD 常开。
