port 4-a: text input through CPythonIME (login typed, in-game chat)

- UserInterface/PythonIME(+Module) ported verbatim; ime module stubs removed, initime() after initdbg()
- EterLib/IME.cpp in platform/: 40250 buffer/WMChar bodies, IMM/TSF processors no-op; committed
  multi-byte text via PythonBoot::UIChar emulating GCS_RESULTSTR
- GameApplicationAdapter RunIME* -> CWindowManager; Godot keys -> ui_ime_key/ui_char
- port.login_flow/login_live type the account through the IME; chat CG_CHAT round-trip on the fake server
- python_game_render_test logs in with Godot key events

    批次 3-b EffectLib（2026-09-24）：`EffectLib/` 18 个 .cpp 原样移植（EffectManager、EffectData/Instance、EffectMesh、粒子系统、SimpleLight 等），删除 `platform/EffectLib` 生成的桩骨架；唯一改动是 `Type.h` 里 `BILLBOARD_TYPE_2FACE` 行尾注释的 `\` 被 clang 当作续行吞掉下一行，去掉反斜杠。`platform/EterBase/Utils.cpp` 剩下的 21 个桩按 §3 照抄 40250 函数体（`GetOnlyPathName`/`IsGlobalFileName` 缺失会让 .msf 以相对名挂的 .mse 丢目录，106 个 RegisterEffect 报错），Win32 调用换成 POSIX 的记 ADAPTED；平台 `CPythonResource` 补上 40250 的 `mde`（CEffectMesh）和 `mdatr`（CAttributeData）资源类型。`port.utils` 覆盖路径/分词/命令行辅助函数；`port.login_flow`：在主角脚下 `CreateEffect(level_up.mse)`，RenderGame 的 `CEffectManager::Render` 录出 levelup_1 贴图的 alpha 混合粒子绘制（dust、dropitem 同样出现）。40250 声明但未定义 `GetRenderingEffectCount`，测试不用。
    批次 3-c CMapOutdoor（2026-09-24）：`GameLib/` 的 Area、AreaTerrain、DungeonBlock、MapBase、MapManager、MapOutdoor（含 IndexBuffer/Load/Quadtree/Render/Update）、MapType、MonsterAreaInfo、Property/PropertyLoader/PropertyManager、SnowEnvironment/SnowParticle、TerrainDecal/Patch/Quadtree，`PRTerrainLib/` Terrain、TextureSet，`UserInterface/PythonBackground(+Module)`，`EterLib/ColorTransitionHelper` 原样移植，删除 pending 替身与 background 模块桩（含 GameplayModuleConstants 里的常量桩）；`EterBase/FileDir`、`TempFile` 在 platform 下照抄 40250 函数体（Win32 查找/临时文件走 common 垫片，记 ADAPTED）。`TEMP_CAreaLoaderThread` 在 40250 已全部注释掉，.cpp 不编（N_A）。手改两处：`CMapManager::BeginEnvironment` 的 `ApplyLight` 标签指针经 `uintptr_t` 转 DWORD；`CTerrainImpl::LoadWaterMap` 按 32 位读 water.wtr 的 `long` 再逐个扩宽（LP64 下 `long` 是 8 字节，否则报 FILE DATA SIZE 16392 != 16400）。平台文件：HTP/STP 地形绘制与 `RenderWater` 为空（地形仍由 Godot 适配层画，§3），STP 的 Initialize/Create/Destroy、水面贴图载入、角色阴影贴图创建照抄；`BeginRenderCharacterShadowToTexture` 返回 false（记 DIVERGENT）。录制设备补齐 `CreateTexture/VertexBuffer/IndexBuffer/DepthStencilSurface`、`Get/SetRenderTarget`、`LightEnable`、`Clear`（CPU 表面/贴图），离屏渲染目标的绘制丢弃，light0 只在启用且为方向光时记录。小地图：`CPythonMiniMap` 在正交投影下画 minimap.dds 瓦片并以 stage 1 相机空间坐标 × `D3DTS_TEXTURE1` 采样 `minimap_image_filter.dds` 做圆形遮罩——录制设备把「正交投影 + 未变换顶点」的绘制按四边形转成 UI 命令（带 mask 贴图与四角 mask uv），`UIRenderAddImage` 按 D3DTS_WORLD 平移、按 TFACTOR 调色（标记点），`python_ui_surface.gd` 用按序的子 canvas item 画 UI 流，带遮罩的图各用一个 shader 材质。`port.login_flow`：Warp 后 `IsMapOutdoor()`、`miniMap.GetAtlasSize()` 已载入、`background.GetCurrentMapName()` 非空；`python_game_render_test` 新增「minimap tiles drawn through the filter mask」（9 块）。截图里主角旁地上的剑是假服 entergame 时按 `GC_ITEM_GROUND_ADD` 放的地面物品（vnum 19，P3-b 拾取测试用），不是武器挂点问题；假服角色没装备武器。
    默认路由切换（2026-09-24）：`client_main` 不设 `MT_PORT_PATH` 时走 port 路由（`python_ui_surface.gd` + `python_3d_surface.gd` 跑 40250 system.py），`MT_PORT_PATH=legacy` 回到 GDScript `AppFlow`，规则见 §2「迁移方式」。已验证：实例化 `client_main.tscn`，默认/`port` 起 PythonUISurface + Python3DSurface 并产出 UI 命令，`legacy` 起 AppFlow + NetTrace。下一步：port 路由稳定后删除 legacy 宿主与开关。
+   批次 4（2026-09-24 起）：补齐 port 路由的玩法，以便删除 legacy。顺序：4-a 文字输入 → 4-b 战斗 → 4-c 商店 → 4-d 任务/NPC 对话 → 4-e 仓库 → 4-f 好友/公会/公会标记 → 4-g systemSetting → 4-h 声音。
+   批次 4-a 文字输入（2026-09-24）：`UserInterface/PythonIME.cpp` 与 `PythonIMEModule.cpp` 原样移植（仅把 MSVC 专有的 `unsigned char(x)` 函数式转换改成 C 式转换），删除 ime 模块桩，`initime()` 按 40250 顺序在 `initdbg()` 之后，`CPythonApplication::Create` 按原序 `CPythonIME::Create` + `SetText("", 0)`。`EterLib/IME.cpp` 在 platform 下：缓冲区、光标、`WMChar`（退格、`|` 转义、按输入代码页 `MultiByteToWideChar`）、候选/读音状态、数字/字符串模式等函数体照抄；IMM/TSF 在 Godot 下没有对应物，组字相关处理器为空、`EnableIME` 恒关，已提交的非单字节文本由 `PythonBoot::UIChar` 模拟 `GCS_RESULTSTR`（`InsertString` + `OnUpdate`），`DelCurPos` 用 memmove 替代重叠的 wcscpy（全部记 ADAPTED）。`GameApplicationAdapter` 的 `RunIME*` 转发到 `CWindowManager`；注意 `RunIMEUpdate/RunIMEKeyDown` 只送达正在渲染的活动窗口（登录框未打开时输入被丢弃）。Godot 侧 `python_ui_surface.gd` 把按键送 `ui_ime_key`（VK）再送 `ui_char`（unicode）。`port.login_flow` 与 `port.login_live` 打开登录框后逐字键入账号（含 LEFT/DELETE/BACK 编辑）、TAB 切到密码、RETURN 登录（凭据只来自环境变量，测试随后删除 Python 局部变量）；进游戏后 RETURN 打开聊天、键入 hello、RETURN 发出 `CG_CHAT`（假服回显 `GC_CHAT`），空行 RETURN 关闭聊天（40250 发完后只清空、不关闭）。`python_game_render_test` 用 Godot 按键事件走同一路径登录。
 
 每个切片都必须同时跑 legacy/port 双路回归；默认路由已切到 `port`（2026-09-24）；port 路由稳定后删除总开关和剩余 legacy 宿主。
