Siavash Sameni d89376016a fix(build): sign release APKs with project keystore (wzp-release.jks)
Release builds from cargo-tauri are unsigned. After Gradle produces the
APK, zipalign + apksigner now sign it with the release keystore
(android/keystore/wzp-release.jks). Falls back to debug keystore if
release is missing.

# WZ Phone — Tauri 2.x Mobile Android APK build
#
# Builds the desktop/ Tauri app as an Android APK via cargo-tauri inside the
# wzp-android-builder Docker image on SepehrHomeserverdk. Uploads the APK to
# rustypaste, fires ntfy.sh/wzp notifications at start + finish, and SCPs the
# APK back locally.
#
# Same pattern as build-and-notify.sh but for the Tauri mobile pipeline:
# - Source: desktop/src-tauri/ (not android/)
# - Build: cargo tauri android build (not gradlew assembleDebug)
# - Output: desktop/src-tauri/gen/android/.../*.apk
#
# Usage:
# ./scripts/build-tauri-android.sh # full pipeline (debug, arm64 only)
# ./scripts/build-tauri-android.sh --release # release APK
# ./scripts/build-tauri-android.sh --no-pull # skip git fetch
# ./scripts/build-tauri-android.sh --rust # force-clean rust target
# ./scripts/build-tauri-android.sh --init # also run `cargo tauri android init`
# ./scripts/build-tauri-android.sh --arch arm64 # arm64 only (default)
# ./scripts/build-tauri-android.sh --arch armv7 # armv7 only (smaller APK)
# ./scripts/build-tauri-android.sh --arch all # both arm64 + armv7 (separate APKs)
#
# Environment:
# WZP_BRANCH Branch to build (default: feat/desktop-audio-rewrite)
