Subject: [PATCH] Bring the jump back so the key warp can reach high ledges

Space is bound to jump again, exactly as before: same action name, same physical_keycode 32, same jump_velocity -190 and gravity 980, so the measured jump height is 20.07 px, identical to the reading taken before the binding was removed. Single jump only, no double jump. The debug flight goes back to Space for up and S for down like it used to, with the arrow keys kept as an extra. No gameplay content touched.

 - **重力**：`get_gravity()`，只在 `not is_on_floor()` 时累加到 `velocity.y`
 - **水平移动**：`Input.get_axis("move_left", "move_right")` 取方向，用 `move_toward()` 做加速 / 减速插值，手感比直接赋值柔和
 - **跳跃**：`Input.is_action_just_pressed("jump")` 配合 `is_on_floor()`，因此**只有踩在地面上才能起跳**，天然不会二段跳
-  - ⚠️ 目前输入映射里的 `jump` **没有绑定任何按键**（空格被空置了），所以这段代码暂时不会触发。
-    想恢复：`项目 → 项目设置 → 输入映射 → jump → 添加按键 → 空格`，或者把 `project.godot` 里
-    `jump` 的 `"events"` 改回 `[Object(InputEventKey, ... "physical_keycode":32 ...)]`。
 - **朝向**：根据 `velocity.x` 的正负翻转 `Sprite2D.flip_h`
