Build a native smalruby3 binary that wraps SDL_main + ruby_init, solving the macOS main thread requirement for SDL2. Users can run scripts with `smalruby3 script.rb` instead of `rsdl`. - ext/smalruby3_launcher/: C source and extconf.rb (based on rsdl) - gemspec: add launcher as second extension - .standard.yml: exclude extconf.rb from lint (mkmf globals) Closes #403 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
smalruby3コマンドを gem に内蔵。rsdl の別途インストールが不要に。macOS では SDL2 が Cocoa のメインスレッドで初期化される必要があり、通常の
rubyコマンドでは segfault する。rsdl と同じ仕組み（SDL_main + ruby_init + ruby_run_node）を smalruby3 gem 内にバンドル。使い方
変更点
ext/smalruby3_launcher/: C ソース + extconf.rb（rsdl ベース）smalruby3.gemspec: launcher を追加 extension として登録.standard.yml: extconf.rb を lint 除外（mkmf グローバル変数）.gitignore: ビルド成果物を除外Closes #403
