wolf: pre-download GE-Proton at install time, auto-extract on start
GE-Proton is required for EA games but was a manual step users had to remember after first Steam launch. This change eliminates that gap: - install_wolf() downloads the GE-Proton tarball to ~/docker/wolf/ge-proton-cache/ during initial setup (~500 MB, runs before the "Start Wolf now?" prompt so it's ready immediately) - _cache_ge_proton() helper in manage.sh does the same on demand - ge-proton subcommand checks the cache dir first and extracts from there instead of re-downloading (~instant vs ~500 MB download) - start subcommand auto-extracts the cached tarball into Steam's compatibilitytools.d if Steam has already launched at least once, so GE-Proton appears in the Compatibility dropdown without any manual ./manage.sh ge-proton step Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01D8ckUJQtj1pH8jtAddBDZs
