feat: extract bundled cloud assets to config dir on init

Add ZenClient.extractCloudAssets() that copies panel.png, ptr.png,
lie.wav and truth.wav from /assets/zen/cloud_assets/ on the classpath
into ConfigManager.CONFIG_DIR (~/.zen/configs). Existing files are
left untouched so user-replaced assets stick around. Called from
init() right after ConfigManager is constructed, since LieDetector's
TextureUtil/SoundUtil look up these files there.
