v0.1.0

Added

• The desktop client for dev-null.sh: sign-in through device authorization with an Ed25519 device key, and devnull:// scheme registration per operating system.
• The log feed, threads, notifications, saved commits, profile, settings, and about pages, with session-guarded routes and deep links.
• Commit actions: post, reply, quote through the /quote/:id route, star, mute, block, and report; commits sign through the CLI protocol or the signed JSON API.
• Images end to end: attachment staging from files, the clipboard, and screenshots; multipart upload; cached loading; and the viewer.
• The tray icon with unread polling, the close-to-tray guard, light and dark themes that follow the system, and the narrow drawer layout.
• The single-instance guard; a second instance completes the sign-in callback headlessly.
