v0.27.4 - file paths shown correctly

This release fixes how file paths are shown.

Paths in the log and in error messages used to come out with every backslash doubled, so C:\Users\You\Documents\report.docx read as C:\\Users\\You\\Documents\\report.docx. Seventeen messages were affected, in both languages. Nothing about how files are shredded changed - this is what you read, not what the program does.

Everything else is the same as v0.27.3: drag files or folders onto the window, review the queue, press Start.

ShredFiles-Admin.zip - requires Administrator (needed for the TRIM/free-space-wipe media phase).
ShredFiles-NoAdmin.zip - runs as a normal user, core wiping unchanged.

v0.27.3 - native GUI, in-app auto-update

Native Fyne GUI replaces the console UI: drag files/folders onto the window (or use the file/folder picker buttons), review the queue, click Start, watch live progress and a scrolling log, done.

• In-app auto-update: checks GitHub Releases on startup, downloads and SHA256-verifies before installing.
• Localized to Russian/English (auto-detected from Windows).
• Engine itself unchanged from earlier releases (scan -> wipe -> cleanup -> TRIM, adaptive passes, Shellbags/RecentDocs/Prefetch cleanup).

See README.md for the full feature list and Known limitations.
