Krzysztof kuhy Rudnicki aa37852296 phone_guard: lease or block raw adb; android_ui drives a session's own virtual display
A raw `adb shell input tap` took no lease, so one session's tap landed in
another session's app (2026-09-25). python_pkg.phone_guard classifies every
adb call in a Bash command and, as the Claude Code PreToolUse hook, takes
the matching phone_lease (one app / real screen / whole phone) or exits 2:
key/text input without -d, input on another session's virtual display, or
a lease still held elsewhere after 40 s.

android_ui gains --display self|<id>: it drives only this session's
phone_vd display under that app's lease, and every input carries -d.
uiautomator sees display 0 only, so virtual-display trees come from a tiny
instrumentation APK (A11yDump.java) built from source without Gradle.

Prunes the oldest evidence artifact to stay under the 60-file cap.
