#Requires -Version 5.1
<#
  Windows-natives Pendant zu bootstrap/neovim.sh (macOS/FreeBSD).
  bootstrap/neovim.sh bleibt unveraendert - dieses Skript ist bewusst
  eigenstaendig, da sich die Paketquellen (winget/npm statt brew/pkg) und
  das Fehlerverhalten zu stark unterscheiden fuer ein gemeinsames Skript.

  Nutzt ausschliesslich native Windows-Werkzeuge (winget, npm, pwsh/
  powershell.exe) - keine Git-Bash- oder WSL-Abhaengigkeit.

  Aufruf (PowerShell, keine Admin-Rechte noetig):
    .\bootstrap\neovim-win.ps1

  Hinweis: Einzelne winget-Paket-IDs (v.a. GnuWin32.Gawk, GnuWin32.Libxml2,
  google.yamlfmt, mvdan.shfmt, astral-sh.ruff, zig.zig) konnten in dieser
  Session nicht gegen eine aktuelle winget-Quelle verifiziert werden.
  Schlaegt eine Installation fehl, meldet das Skript das als Warnung
  (bricht nicht ab) und nennt den Befehl zum manuellen Nachschlagen
  ("winget search <name>").
