bootstrap: neovim-win.ps1 hinzugefuegt (natives PowerShell-Pendant)

Reiner PowerShell-Weg statt Git-Bash/WSL, wie von Thomas gewuenscht.
Installiert Formatter/Tools/LSP-Server per winget und npm; einzelne
fehlschlagende Pakete werden als Warnung gemeldet statt das Skript
abzubrechen (mehrere winget-IDs konnten in dieser Session nicht gegen
eine Live-Quelle verifiziert werden, siehe Kopfkommentar im Skript).

neovim-windows-setup.md: Abschnitt zu externen Abhaengigkeiten auf das
neue Skript verweisen lassen statt einzelne Befehle aufzulisten.

+<#
+  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>").
