修复 LightGame 玩家地面抖动、动画切换异常并完善 spike/终点视觉
## 物理与动画（核心修复） - PlayerController::update：地面状态下跳过 apply_gravity。之前每帧重力累入 velocity.y，sub_pixel_y_ 会缓慢累到 ≥1000 像素阈值，导致玩家下沉 1px 后被 collide_tilemap 推回，每隔几帧抖动一次。这是"动画机切不回 idle"的真正根因 —— 单帧 grounded=false 让状态切到 Falling，下一帧又回 Idle，视觉表现为 idle/fall 帧间歇错位。 - Physics2D::collide_tilemap：发生轴向推回时清掉对应 sub_pixel_x_/y_，防止小数残留在下一帧继续推进位置。 - Physics2D::is_grounded：feet 探测窗口（max.y..max.y+2）跨越的所有 tile 行都要扫描，而非只查 feet.min.y/ts 那一行。原写法在边界帧（feet.max.y 临时为 31n+0）会错把上一行空 tile 当判定行返回 false，触发上述的单帧 Falling 抖动。 - PlayerController::update：grounded && velocity.y >= 0 时无条件清零 velocity.y（不再要求 !was_grounded_），避免重力残留导致连续下沉。 ## Spike 行为 - Physics2D::is_tile_solid：spike(tile id 4) 改为非实体，玩家可踩入触发死亡。原先 spike 与普通地块都被当 solid，玩家停在 spike 顶部不会死。 - PlayerController::check_death：spike 击杀区域收紧到 tile 底部 14px（视觉高度），不再用整 32px tile 误判。 ## 关卡视觉（出生点 / 检查点 / 终点） - LevelLoader：玩家出生点附近生成 flag 装饰对象；Checkpoint 触发器初始显示 checkpoint 精灵，被激活后由 LightGameApp 在 check_triggers 中替换为 flag 精灵；LevelComplete 触发器使用 checkpoint 精灵作为终点。 - LevelLoader 暴露 flag_sprite() 静态访问器，供 LightGameApp 触发激活时复用同一份 sprite 引用。 ## 资源与配套 - 重新打包 tile_atlas（重新生成 generated/tile_atlas.h），更新 assets/tile/checkpoint.png、flag.png 的视觉素材。 - Level1Data、LevelEditor、LevelRenderer、GameObject、tests 跟随接口调整同步更新；game_engine_tests 重新编译通过。
