0.20.0

• A native GNOME desktop client for Linux. unrager now has a fourth native face — a GTK4 / libadwaita desktop app (linux/, built with relm4) beside the iPhone and Mac apps. Like them it's a thin client over unrager serve: it auto-spawns or reuses a local server, or points at one over Tailscale. It carries every source, threads, profiles, compose/reply, optimistic like, a paging media viewer, notifications with desktop banners, and the rage-filter / ask / brief / translate features — all in a real Adwaita window. Inline photos fill the tweet column at their true aspect (with a Compact/Standard/Large media-size preference); video and GIFs show a poster with a play badge; every screen has proper loading/empty/error states; and a right-click menu copies or saves any image. Adjustable text size, light/dark/system appearance, and circular adw::Avatars throughout. Build it with cd linux && cargo run -p unrager-gtk (needs the GTK4 + libadwaita dev packages). It's a separate GUI workspace and isn't published to crates.io; see linux/README.md.
