fix(tauri): provide native About menus

Replace the inert macOS About handler with Tauri's native About item using the packaged application version and CodeNomad metadata. Add a conventional Help menu on Windows and Linux so the same application information is available across desktop platforms.

Expose the latest GitHub release as Get Updates in each platform menu. Windows and Linux also show the update link inside the native About dialog; macOS keeps the separate menu action because its native dialog does not support website metadata.

Validated with all 21 Tauri Rust tests, cargo check, git diff checks, and an independent gatekeeper review.
