release: v0.1.6 — uinput-first injection, window-switch fix, Telex disabled

- uinput injection is now primary on X11 (XTest fallback)
- X11 XTest keycode offset +8 fixed for all send_keycode paths
- Window switch detection on every keystroke (no more gap > 100ms guard)
- Telex greyed out in tray with '(next version)' label
- Flatpak and AppImage removed; only .deb packaging
- All Cargo.toml versions bumped to 0.1.6

 # Changelog
 
+## v0.1.6 (2026-06-29)
+
+### uinput-First Injection
+
+- **Injection priority reversed**: uinput (`/dev/uinput`) is now the primary injection backend on X11, with X11 XTest as fallback. uinput sends evdev keycodes that route correctly through libinput — no X11 keycode offset needed.
+- **X11 XTest keycode fix**: X11 injector was sending evdev keycodes directly to `XTestFakeKeyEvent`, which expects X11 keycodes (evdev + 8). Backspace sent keycode 14 (evdev) = X11 keycode 14 = "5" key. Fixed by adding +8 offset in all `send_keycode` paths.
+- **`paste_via_clipboard()` backspace fixed**: was hardcoded to X11 keycode 14 (actually "5"), now uses evdev 14 + 8 = 22 (correct X11 backspace).
+
+### Window-Switch Detection
+
+- **Active window ID verified on every keystroke**: removed the `gap > 100ms` guard — the daemon now polls `xdotool`/`xprop` directly for every character keypress. This catches window switches that complete in under 100ms, preventing old engine buffer from leaking into the new window.
+
+### Input Method
+
+- **Telex disabled in tray**: greyed out with "(next version)" label and `Disposition::Informative`. Only VNI is functional.
+- **Default input method changed** from `"telex"` to `"vni"` in config fallback.
+
+### Packaging
+
+- **Flatpak and AppImage removed**: only `.deb` packaging is maintained. `packaging/flatpak/` and `packaging/appimage/` directories deleted.
+- **Postinst improvements**: removes stale `/usr/local/bin/vietc*` binaries, deletes old `~/.config/vietc/config.toml` + `overrides.toml` + `.first-launch-done`, shows logout popup (notify-send + zenity).
+- **CI workflow**: only `.deb` artifact collected (no AppImage).

 ## Installation
 
-### Flatpak (recommended)
+### Debian Package (recommended)
 
-System tray icon + daemon. Find **"Viet+"** in your app menu to launch, or run from terminal.
+System tray icon + daemon + desktop entry. Requires user to be in the `input` group for keyboard capture.
 
 ```bash
 # Install
-flatpak install --user --bundle VietPlus-x86_64.flatpak
+sudo dpkg -i vietc_0.1.6-1_amd64.deb
 
-# Launch via app menu, or:
+# Log out and log back in (for input group membership to take effect)
-flatpak run io.github.vietc.VietPlus
+# Then launch "Viet+" from your application menu
-
-# Uninstall
-flatpak uninstall --user io.github.vietc.VietPlus
 ```
 
-Includes daemon + CLI + system tray + uinput daemon. Sandboxed — no system libraries are touched.
+The post-install script will:
+- Kill any running tray/daemon processes
+- Remove stale binaries from `/usr/local/bin/`
+- Add your user to the `input` group
+- Prompt you to log out and back in

-## Key Notes
-
-- **SDK/RUNTIME order**: `flatpak build-init` takes `SDK` first, then `RUNTIME` (counterintuitive but important — getting this wrong means `/usr/lib/sdk/` won't be mounted)
-- **Rust SDK**: must be installed as `org.freedesktop.Sdk.Extension.rust-stable//25.08`; it mounts automatically at `/usr/lib/sdk/rust-stable/`
-- **Icons**: all icon files in Flatpak must be prefixed with the app ID (`io.github.vietc.VietPlus.*`) or `flatpak build-export` will skip them
-- **Daemon binary name**: Cargo builds the daemon binary as `vietc` (not `vietc-daemon`) in `target/release/`; rename on install to match the desktop file
-- **Desktop Categories**: only use registered categories (`Utility`); `InputMethod` is not registered
