Fix portable Python: ship python/runtime and relink .venv on install (0.4.6).

0.4.5 venv pointed at the build machine user profile; other PCs failed to start API.
Bundle stdlib under python/runtime, repair pyvenv.cfg, and health-check before start.

-**Offline:** Setup ships portable PostgreSQL, `.venv` (when built with `-CreateVenv`), and WinSW. The installer wizard chooses **built-in or external** PostgreSQL and validates external credentials (`psql SELECT 1`) before files are installed — **no GitHub/EDB download on the target PC**. Service install uses bundled WinSW (pass `-AllowDownload` only on a build/dev machine if the binary is missing). Auto-update still needs network later, and is unchecked by default.

 **OS:** Windows 10/11 or Windows Server **2016+** recommended. Packaging scripts are UTF-8 **with BOM** so Chinese UI works on Windows PowerShell 5.x. Bundled Python in current releases is **3.13+**, which does **not** support Windows Server 2012 R2 — use Server 2016+ or a newer desktop OS.
