add an Android Quick Settings tile for starting and stopping EasyTier VPN networks
persist tile actions until the Tauri frontend is ready, so cold-start clicks are not lost
add the standard Quick Settings preferences activity alias so long-pressing the tile opens EasyTier
keep network and VPN lifecycle ownership in the existing frontend reconciliation flow
Add a root .gitattributes pinning *.sh to LF so shell scripts stay
executable after a checkout on Windows with autocrlf enabled; without
it every .sh lands in the working tree as CRLF and fails when run
under WSL/bash.
Also ignore tauri-plugin-vpnservice/android/.gradle, which Gradle
regenerates on every sync.
