Add scripts/build_phone.sh: real-phone APK build (arm64+arm)

Browse Source 
Same pipeline as build_emu.sh (gogio -> apktool MANAGE_EXTERNAL_STORAGE
injection -> debug-sign) for a real phone: -arch arm64,arm (covers any
phone from the last decade; gogio accepts a comma-separated arch list)
and output cmd/pad/pad-phone.apk. Notes in the header: on Android 11+
the user must grant 'All files access' in system settings after
installing (MANAGE_EXTERNAL_STORAGE is app-restricted; the emulator AVD
had it granted, phones do not).

# Build the Pad Android APK for a real phone (arm64 + arm), optionally
# installing it to a connected device.
#
# Usage:
# ./scripts/build_phone.sh # build + install to the connected device
# ./scripts/build_phone.sh --no-install # build only
#
# Output: cmd/pad/pad-phone.apk
#
# Same pipeline as build_emu.sh (gogio -> apktool permission injection ->
# debug-sign); the only differences are the architectures (arm64,arm covers
# any phone from the last decade) and the output name. On Android 11+ the
# user must grant the app "All files access" in system settings after
# installing (the MANAGE_EXTERNAL_STORAGE permission is a special
# app-restricted permission; the emulator AVD granted it, phones do not).
