Subject: [PATCH] Add SessionStart hook to install Android SDK and warm Gradle
 cache

Installs Android SDK command-line tools, platforms;android-36, and
build-tools;35.0.0 via direct wget downloads (sdkmanager cannot resolve
packages through the proxy in remote sessions). Also warms the Gradle
dependency cache. Only runs in CLAUDE_CODE_REMOTE=true environments.
