feat(android-agent): Meilenstein 1 — verbinden + in Diagnostic sichtbar

Nativer Kotlin-Agent (host-agent/android/): Gradle-Projekt, AndroidManifest, RVS-WebSocket-Client (OkHttp) mit host_hello/host_ping/host_command->host_result, Foreground-Service (Weg A, Auto-Reconnect, BootReceiver), Connect-UI (QR-Scan via ZXing ODER manuell: host/port/token/name/TLS/Steuerung-Schalter). QR-Format = {host,port,token,tls} wie die ARIA-App -> derselbe QR nutzbar. M1-Aktion: info (Modell/Android/Akku). screenshot/ui_* liefern 'kommt in M2/M3'. Gate: CONTROL_ENABLED-Schalter in der App. Build: Docker (Android-SDK+Gradle) -> dist/aria-android-agent.apk (Debug, auto-signiert). Kein Google.
