Cristian Cezar Moisés 136a96ed20 docs: complete zupt → vaptvupt rename; README v4.0.0 refresh

- README: add 'What's new in 4.0.0' section, extend release history
  v2.2.4 → v4.0.0, fix stale section titles (benchmark/security/feature
  tables), point fast-install at short.securityops.co/vaptvupt, fix
  related-project links (vaptvupt-codec, libvuptsdk, real repo names)
- install.sh: clone the renamed repo, vaptvupt success message
- Rename remaining zupt → vaptvupt across INSTALL.md, DISTRIBUTION.md,
  SECURITY.md, THREAT_MODEL.md, ROADMAP.md, THIRD-PARTY-NOTICES.md,
  gui/ + sdk/ + packaging READMEs, doc/vaptvupt.1, spec comments/URLs
- New doc/vaptvupt-gui.1 (GUI 1.3.0, VAPTVUPT_BIN/ZUPT_BIN env vars);
  doc/zupt-gui.1 kept as hardlinked compat copy
- Deliberately unchanged: .zupt extension, ZUPT header magic,
  ZUPT-* crypto domain-separation constants, zupt_*/ZUPT_* code
  identifiers, libzuptsdk artifact names, legacy symlink notes,
  CHANGELOG/AUDIT historical entries, Provides/Obsoletes upgrade path
- tests/test_packaging_syntax.sh: THREAT_MODEL section titles updated

VaptVupt GUI — Cross-Platform Post-Quantum Backup

Desktop application for vaptvupt backup compression with ML-KEM-768 + X25519 post-quantum hybrid encryption.

Works on GNU/Linux, BSD, macOS, and Windows.

Install

Linux (recommended)

tar xzf vaptvupt-gui.tar.gz && cd vaptvupt-gui
./vaptvupt-gui                      # auto-creates venv, installs PySide6
./install.sh --user              # adds right-click menu integration

After install, right-click any file in Nemo/Nautilus to see "Compress with VaptVupt". Double-click any .zupt file to open it in the GUI.

Windows

Option A — Installer (recommended):

Download VaptVuptGUI-1.3.0-Setup.exe and run it. Installs to Program Files, adds Start Menu shortcut, desktop shortcut, right-click context menus, and .zupt file association. Includes uninstaller.

Option B — Build from source:

cd packaging\windows
build-windows.bat

Requires Python 3.9+, NSIS 3.x, and a compiled vaptvupt.exe.

Option C — Run directly:

pip install PySide6
python src\zupt_gui.py

macOS / BSD

pip3 install PySide6
python3 src/zupt_gui.py

AppImage (universal Linux)

chmod +x VaptVupt-GUI-1.3.0-x86_64.AppImage
./VaptVupt-GUI-1.3.0-x86_64.AppImage

Flatpak

flatpak-builder --install build packaging/flatpak/dev.zupt.gui.yml
flatpak run dev.zupt.gui

Features

Tab	Function
Keys	Generate ML-KEM-768 + X25519 hybrid keypairs
Compress	All codecs, levels 1-9, dedup, solid, password, PQ keys
Extract	Decrypt and extract .zupt archives
Verify	Check block checksums, view archive metadata

About	Version, cryptographic stack, credits

All tabs support drag-and-drop. Drop a .zupt file anywhere on the window to extract it. Drop any other file to compress it.

System Integration

Linux (Nemo / Cinnamon)

After ./install.sh --user:

Right-click any file: Compress with VaptVupt
Right-click .zupt file: Extract with VaptVupt
Double-click .zupt: opens in VaptVupt GUI

Windows (after installer)

Right-click any file: Compress with VaptVupt
Right-click any folder: Compress with VaptVupt
Double-click .zupt: opens in VaptVupt GUI
Right-click .zupt: Verify Integrity

Architecture

VaptVupt GUI (PySide6, Python)
    |
    |-- subprocess.Popen() with streaming stderr
    |
    v
vaptvupt CLI (Pure C11 binary)
    ML-KEM-768 + X25519 + AES-256-CTR
    VaptVupt / LZHP / Store codecs
    Block deduplication, full-disk backup

The GUI calls the vaptvupt CLI binary — all cryptography runs in native C, not Python.

Packaging

Platform	Format	Tool
Any	pip	`pip install .`
Debian/Ubuntu/Mint	.deb	`packaging/deb/control`
Fedora/RHEL	.rpm	`rpmbuild -ba packaging/rpm/vaptvupt.spec`
Universal Linux	.AppImage	`packaging/appimage/build-appimage.sh`
