- install.sh: rewritten to download prebuilt tarball from GitHub releases
(or fallback to .deb extraction), removing verbose cargo build output
- release.yml: new CI workflow to build & upload tarball on tag push
- uninstall.sh: add systemctl --global daemon-reload after removing service
- daemon/src/main.rs: fix VNI backspace offset in X11 keymap capture path
(missing +1 adjustment for control keys that reach the app directly)
