Awesome Codex Theme v0.3.0-alpha.1

Updater-signed Tauri Theme Manager beta with ACT Full Skin v1. Windows Authenticode and Apple Developer ID signing/notarization are not included in this beta, so the operating system may show an unknown-publisher warning. macOS bundles carry an ad-hoc signature for package integrity only. The app applies verified backgrounds, materials, colors, and theme copy without modifying ChatGPT application files.
