; --- PORTABLE MODE --- Auto-detect portable mode during updates.
; If the target directory already has a valid portable marker file, preserve
; portable mode so the Tauri updater works without needing /PORTABLE.
; We validate the magic string to avoid false-positives from stale empty files
; left by scoop's NSIS extraction (dl.7z side-effect).
; Preserve portable installs that use either the current magic-string marker
; or the legacy empty marker created by older Handy releases. Require Data/
; for the legacy empty-marker case so stale scoop side-effect files do not
; accidentally opt an updater run into portable mode.
