Adds an opt-in Tor mode that routes all app traffic through a local SOCKS5 proxy backed by arti (Tor in Rust), bundled via the org.torproject:arti-mobile:1.7.0.1 AAR. - TorController starts/stops arti and installs a fail-closed WebView proxy override (no direct fallback) so traffic can't leak while Tor is connecting or down. Connectivity is verified against check.torproject.org (IsTor) and re-checked continuously; the exit IP is surfaced for verification, and the status isn't latched so a dropped circuit downgrades honestly. - TorPlugin bridges enable/disable/status to the Capacitor/JS layer. Toggling applies live, in place, with no app restart. - UI: a slim fail-closed status banner (replacing the old full-screen gate), the Tor toggle in Advanced settings reachable while logged out, and Settings/Search/About added to the logged-out menu. - R8 keep rules for org.torproject.arti.** so the JNI native-method classes aren't stripped/renamed; androidx.webkit on the compile classpath for the WebView proxy APIs.
