docs: 目标平台收窄为 macOS arm64 + Android arm64

用户决定:Linux 和 Windows 不做,不验收、不作为任何步骤的阻塞项。

- PORT-PLAN 第 1 节写明范围;2A step 3 的平台列表、2P step 1/2 措辞跟着改;
  2P step 4 由「五个平台分别验证」改为「两个目标平台」,Linux/Windows 两行
  划掉但保留原因备查(上游 2.7 只支持 MSVC + PC/pyconfig.h,mingw 下
  posixmodule.c / dynload_win.c 与 MinGW 头文件冲突)。
- PLATFORMS.md 新增 Scope 段;THIRD-PARTY.md 的 CPython Windows 段由
  "not built yet" 改为 out of scope;PYTHON-EMBED-EVAL.md 下一步两条。
- 仓库里的 mingw-w64 交叉编译只留作可移植性门禁(它抓到过
  UserInterface/StdAfx.h 的真问题),不代表支持 Windows。
- iOS arm64 暂按次要目标记录:保持交叉编译干净,但不作为验收目标。

仅文档改动。port_map.py check 0 error;参考 EterPack.cpp 的 8 个 pack key
值逐个 git grep --cached -w,均未入库。

come from Homebrew are now vendored and cross-compile from the same tree — see
`docs/THIRD-PARTY.md`.
**Scope (decided 2026-09-23, PORT-PLAN §1):** the shipping targets are **macOS
arm64** and **Android arm64**. iOS arm64 stays cross-compile-clean but is not an
acceptance target. **Linux and Windows are not done** — the mingw-w64 cross
build is kept only as a portability gate (it catches real include/layering bugs),
not as Windows support, and MSVC is not built at all.
