 `-ErrorAction SilentlyContinue` rend l'étape idempotente (pas d'erreur si rien ne tourne, cas d'install propre). Le `Start-Sleep` 500ms laisse Windows libérer le file handle. Le snippet officiel passe à 6 lignes ; une note explicative est ajoutée dans la section *Install* du changelog généré.

@@ -168,6 +981,52 @@ Double correctif :
 
 Conséquence : les sous-commandes CLI (`muyue scan`, `muyue version`, `muyue install-shortcuts`) ne produiraient plus d'output quand lancées depuis cmd.exe. Mitigation : nouveau fichier `cmd/muyue/console_windows.go` qui appelle `kernel32!AttachConsole(ATTACH_PARENT_PROCESS)` au démarrage. Si un terminal parent existe, on s'y rattache et `os.Stdout` / `os.Stderr` / `os.Stdin` y sont rebindés ; sinon, on tourne silencieusement (cas double-clic). Compatible des deux usages sans deux binaires séparés.
