v1.1 — GTK4 Settings GUI & Iterative Enrollment

What's new

GTK4 Settings GUI (face-auth-gtk)

• Live IR camera preview with face-detection overlay
• Camera picker dropdown for IR device selection
• Similarity threshold slider (0.1–0.95)
• Enroll Face button — captures and stores 5 face embeddings
• Improve Matching button — appends new embeddings without replacing existing ones
• Test Authentication button — captures a single frame and compares against stored embeddings
• Automatic config persistence to ~/.config/face-auth.toml

CLI

• face-enroll --improve — append embeddings for better recognition across different lighting/angles

Deployment

• deploy-gui.sh — installs the optional GUI (detects immutable FS, uses ~/.local paths on read-only /usr)
• uninstall.sh --gui — remove only the GUI components
• All scripts handle immutable distros (Bazzite, Bluefin, Silverblue, Kinoite)

Full changelog

• feat: GTK4 settings GUI with live IR preview, deploy-gui.sh, and comprehensive README update
• feat: add --improve flag to face-enroll and Improve Matching button to GUI for appending embeddings
